it depends which altcoins we're talking about, the scam ones will never see bottom, it will see nothing and your investment go to zero. that's the bottom.
You are absolutely tight. The scam coins will never see the light of the day and people who invested in them will never recover their losses. I am talking about the good alt coins which will certainly go 10 t0 100X
Ongoing signs proves us that a new uptrend is starting and it will actually be very impressive around 2021, in 2020 see the defi trend we have seen many projects. It grew terribly fast, and by far the hype about defi was no longer common. The Defi projects are running out of money and I see everyone looking at BTC right now, maybe it's not time to get started with altcoins but soon we will see altcoins increase BTC.
