I was going to buy a bitcoin or two in 2013 when it was $400 and my co-workers at the time, but darn I didnt.
Selling them for way more than I bought them.
Regarding the article, it is impossible to have an objective view about cryptocurrencies price (not technology) in general but it is creating a lot of millionaries down the road. I don't know if this will happen to the new entrants but it happened to the ones who bought and haven't sold Bitcoins for less than 4 years. All this have a strong economical impact in your life and the life of many others, probably more people are getting millionaries from cryptocurrencies than from startups.
What I have personally done is to take out small chunks whenever Bitcoin increases, 1% maybe or even less of the total bitcoin I own and treat myself to something nice like a new desktop perhaps.
Lately some of my coworkers have started using mobile wallets for Bitcoin and it is common for us to pay each other if someone pays for everyone in fiat for lunch for example. It's still hard to find places that accept Bitcoin but I see it popping up here and there which is pretty cool.
It went up to 17000$ exactly because people like you didn't buy it. If everyone bought a bitcoin we'd be looking at perhaps 0.01 per btc.
It's like people feel that 5 is the best number to place their bets in that one roulette machine and they wish they had learnt of it a year ago. And adding to the misery now there is a huge line blocking everyone trying to cash out their chips.
It's more of an investment for them, I'm not sure if they actually use BTC to buy anything.
