At the risk of this answer not aging well...
Crypto is at an interesting spot right now. Stripe just dropped BTC and more and more people are realizing there may be better alternatives to what BTC provides. The problem is BTC has so much market share.
Here are my fairly uneducated opinions/guesses.
Assuming the entire crypto market doesn't get killed from regulations or Tether...
XLM will thrive as it has a real product and a real team behind it. If I put on my conspiracy hat I'm predicting Stripe adds support for it, Reddit uses it to power Reddit Gold, and Coinbase adds it in 2018. I think those YC ties run deep.
ETH will continue to grow and will eventually beat out BTC.
Others I like right now are VEN, ICX, NEO.
"Coins" backed by real teams and real products will thrive. Everything else will die. The problem is I hope the ones with the real teams and products aren't brought down by the imminent doom that's going to happen with all the sketchy coins dying.
So, is it a bubble? Yes. But so is student loan debt, the national debt, etc etc etc. The more important question is when will it pop?
