The only thing that is certain is BTC will continue to make all-time highs. Will alts survive? Not all of them. Will tron reach 7$ someday? Impossible to tell, but if the hype is mirrored with development, it could see big increases, just like we saw with ETH.

Investing in BTC is the safest bet, investing in STEEM or TRON might make you rediculously rich if you have 3-10 years of time.
