In my opinion, Bitcoin has the first mover advantage in this space. It was the first real use of the blockchain, is still the gateway to pretty much every other crypto currency, there is a maximum supply of coins, and is one of the only coins that can be purchased/exchanged for US dollars (or other fiat currency). In order to purchase an altcoin such as BAT (the token behind the brave browser the article refers to), you have to first purchase Bitcoin. If you want to sell your BAT tokens, you will receive Bitcoin.
Also Bitcoins do cost real money to actually mine (electricity costs).
Other tokens such as Ethereum are gaining popularity as well and have some advantages over Bitcoin, but I don’t see Bitcoin being displaced anytime soon.
In the case of Ethereum, the value is that the token is used as “gas” on the Ethereum network. Any action you want to take or data you want to store will require that you send a certain amount of Ether in order to perform that task. Since Ethereum is a platform that many of these ICO companies are building apps on top of, it stands to reason that the value of the platform should be greater than the value of the company building on top of it.
As of right now, you are right. The entire crypto market is speculative. I think a platform like Ethereum has a better chance of being valuable than a random token that someone with no blockchain experience put together a whitepaper for in a few days and then launched an ICO for.
Bitcoin is a global cryptocurrency. Sure it has a first-mover advantage but so does Google. Today someone searches with google, tomorrow they may switch to Bing. Can't the same be said of Bitcoin and say Litecoin / Dogecoin / whatever? So why is Bitcoin worth more than Litecoin let's say? Both are accepted by Coinbase etc.
So one reason BTC is worth more (speaking of entire market cap here) than, say, LTC, is because it is accepted more places.
Another reason is that BTC is perceived (rightly or wrongly) as more stable than other crypto currencies.
But all those legitimate reasons are amplified dramatically right now by speculation.
Does the common man think of "cryptocurrency", or does he think of "bitcoin"? If in that persons head, "bitcoin" is the same as "cryptocurrency", then it will be really hard for a competitor.
Google is a nice example. "I will google it for you". Nobody says "I will bing that", or, sadly for other search engines, "I will search the web". We say "I will google it". In our head, google is the search engine, and the search engine is google. So if bitcoin is in that same ballpark, good luck to the competitors.
But I'm not saying other cryptocurrencies can't bring anything new to the table, such as Ethereum or Monero. But bitcoin definitely has the brand positioning advantage.
Most importantly, the Coin that has the highest expense to "mine" is the most secure. To attack Bitcoin by out pacing the current miners, it would require millions of dollars in hardware which could just as easily be used to legitimately acquire Bitcoin by mining.
However second place is easily attacked, as the case with BCH, the bitcoin attempted fork. Miners are using their hardware to primarily mine Bitcoin, paying for the hardware, then occasionally attacking BCH, to break it's adjustment algorithm.
BAT is an ERC20 token on Ethereum. In order to purchase it you buy Ether, and then go to a decentralized Ethereum exchange like 0x and purchase it. When you sell BAT, you receive Ether.
I am not trying trying to argue about if BTC or ETH is better.
CryptoCurrency is the base primitive of the blockchain, that is consumed to store transactions permanently, as well as to reward the block creators. CryptoAssets are usually extra metadata in transactions that updates some state. The USDT token actually runs on the bitcoin blockchain, on an early 2nd layer network called OMNI. ICO takes the cryptoasset further and issues some 2nd layer token and then resell that for the underlying cryptocurrency. Its a magic bean sale, paid with gold coins.
An ICO on ethereum, for example, is simply a database entry that says your address holds some number of tokens in a contract. You do not own them, you are just tagged as having a certain number. Most contracts have a suicide clause. One authorized (we hope... ooops) method call could nuke that value instantly.
With a cryptocurrency, you control the value stored in unspent transactions. With this you own the private key. No external party can remove those funds with that private key.
That hasn't existed before.
Because these are both embedded into the coin valuation it feels more like stock to me than currency. Specifically it might be like owning stock in eTrade, which has utility value as a platform for trading stock, and an arbitrary value based on consumer demand.
The only reason it is harder to notice with crypto is because the size of the market you can use crypto in is so ridiculously small (relative to a national currency) that investment value and speculative effects dominate.
