For me Alt season is died long time ago and there is no reason to buy some altcoins.
Ethereum and Waves are my favorite and maybe i will buy only 2 alts but i am not sure about that.
Altseason didn`t die, prices dropped since 2017, it`s true, what happened after to BTC happened to many altcoins too. 2018 was a hard year for cryptomarket in generally, but look at this year, we already see signs of recovery. Like always BTC is leading the game, nothing new about that, altcoins are trying to keep up and many altcoins made some progress.
Ethereum and Waves are altcoins, there are many other good ones too. Accumulate in what you believe in, it`s what I do.
