well, maybe for some altcoins, their team will try to make the price of the coins they own go up. they do that to keep investors comfortable, and not bothered by the existence of FUD. however, I think there will be some projects that won't pump their coins. whether it's good or not but I think projects that don't try to maintain the price of their coins will easily be abandoned by investors. only, the increase in the price of the coins they have will not make the price of their coins recover. it's probably only a few percent. some coins may recover, but not all coins will be like that. in this case we can see which investments are good, which ones are quite vulnerable to fall.
Maybe coins will be de listed on some exchanges as well. This bear market is very painful for small projects and to those people who wants to start their project this Q2, a team with good strategic and risk management plan can survive this bear market, I believe that after this Q2 and Q3 we will going to have green market again this Q4.
Yes it can happen, every exchange needs to clean up their platforms and they are regularly delisting dead coins or coins with less to no volumes at all. Big coins have suffered a lot from this bear and how much more those small projects? I think they are the ones that have badly beaten up.
For those who are planning to launch their own projects, this cant be a good time to do it but it would be better if they will released it once the market have recovered. Strats, plans and others, cant do anything much in this bear, but bear is too strong that even the strongest projects like btc cant also do anything to help itself but like you I also expect that q4 is going to be better for the market.
