Anyone who accepts Bitcoin runs into the problem where others can know their balance by looking up the address (and thus could be at risk for theft/mugging).
If people want to keep their balances private and not share their transaction history (or later transactions), they should use a coin that's private by default such as Monero.
Additionally, Monero has a dynamic blocksize, so as usage increases it won't experience the transaction backlog that Bitcoin faces.
You didnt say it is not yet in a tagged release, just mentioned no it isnt subadress but multisig, ehich tells me you had no idea
Either way, it doesnt matter.
I am kind of confused with the block size thing. Sure, increasing the size means more transactions can be added into the problem. Bu, as far as I know bigger block size has it's own share of problems - block propagation is slower which can cause double spending and frequent orphans means the blockchain has to keep re-organising frequently too.
Blockchain-based coins are hard to scale. The most scalable ones at the moment use a Directed Acyclic Graph (DAG) instead of a blockchain.
I think that IOTA and Byteball (both DAGs) are the most advanced at the moment in terms of scalability.
In the long term, Ethereum may have potential if they manage to implement sharding.
Another good long term bet is Lisk which aims to scale using sidechains.
This isn't terribly surprising because from the discussions I saw, the entire justification for why it could scale infinitely seemed to boil down to the creator accusing anyone who questioned this of spreading FUD. Byteball may be doing better, but on the other hand it hasn't had the same kind of speculative bubble that's done Bitcoin and IOTA in yet.
I'm sure that IOTA still has issues but I think that the core DAG/tangle concept is sound. Unlike with most other tokens, these problems should be relatively easy to fix... My bet is that it's much easier to scale a DAG than a Blockchain. But I'm sure that some blockchain-based tokens will also scale eventually.
I agree. I researched Ripple a lot and am sold on it, since it's not just a crytocurrency (XRP Ticker) but is also a protocol that Gates Foundation, AMEX and other banks are using to perform cross-border payments almost instantly and with a lot lower fees and overheads.
Are any of the others you mentioned, ex : stellar, dash, monero etc similar to Ripple? If not, what are their use cases? Any links you can point me to would be helpful thank you. (I know I can google this, but google is full of SEO-ed promotional and pump-and-dump posts, so can't really rely on that info).
I recommend reading forum posts about these different currencies to get an idea of what people think are the most competitive features/pitfalls. You could google something like "most scalable alt-coins" and then read stuff from reddit and bitcointalk.org. When a few of them have gotten your attention, do a "x vs. y vs. z" search and read more forums. You kinda have to feel it out!
In short, most altcoins are neither useful for investment nor payment. Which is a shame, because there are some coins that have substantial technical improvements over bitcoin, and nearly all of them can handle more transactions/second than bitcoin
The really big multipliers have been in so called alt-coins for years. This statement is flat out wrong.
