I put a very small amount in late (February) at all time highs. Purely a speculative play, but I wanted to figure out the crypto game and be ready in case it is sensible to put more into. I am starting to understand its potential but the hype around it is very dangerous, lots of personalities manipulating prices, pump and dumping, etc. so it's a gamble. I try to ignore alt coin hype and stick with mainly with BTC and ETH, some side bets with ADA, DOT and DGB. The trading fees and capital gains tax are a bit ridiculous.
