Valid altcoins will never make you disappointed. Probably crypto industry maybe go though a dump before start of bull session but If you want to purchase altcoins now, then thats also okey! If somehow price go below, then price will also raise up soon. So don't worry but be aware to avoid buying altcoins which have Over prices already because of preliminary market pump. Better to have little patient to observe market before purchase.
I think there was more than enough time to buy altcoins; the market was not in the best condition for more than six months for a long time.It was a great time to form your own portfolio and wait for the market to give impetus.Good altcoins will always be in price and will have increased interest in the green market.
