I think now is the right time to invest, because almost all altcoins are at very low prices for now, the altcoin I highly recommend is BNB, because in addition to BNB's price which has almost touched 700$, BNB coin is also a low risk coin.
In general, yes, you are unlikely to lose much if you invest in BNB now, but we do not know how the market will behave in the future, and it may fall or enter flat.
In any case, I agree that BNB at the current price is not such a bad investment.
