The best time to invest in altcoins is bear market, the cheaper you buy the easier you make profits from the coins than buying at a very high price which can take decades for you to make back what you invested not to talk of making profits
What you think now....bull market is over for alts or still looking bullish?
Bull market haven't even started for altcoins, not while Bitcoin is still trying to take back the 10k zone, the last altcoin season came to reality when Bitcoin hit 18k and higher, but still better have patience when trying to buy altcoins
