Even if it is a bubble, it has long time yet before it bursts.

It could take a year, and a 25x rise in total market cap ... or the bubble could burst tomorrow, you never know. I don't own much crypto at the moment, it's a big risk ... but also with big possible rewards.

Also, how much would it fall when the "bubble bursts"? Even a 60% fall in value would leave most cryptos more valuable than what they were some few months ago ...
