Waiting for the market to get fixed like in the old days would takes so much time, and sadly we can't wait that long until it fully recover. So my strategy would be to collect as much coins as i could afford to get through many kind of way possible, and kept them stored until it could generate profit, even if it's just a little.
collect coins and save, you choose good and potentially big coins because there are currently many low prices and you can choose them.
not all coins are good, so you research them before you have them.
good coins will affect when the market grows.
everyone has a different strategy and maybe this is the best, hopefully this way in the future can be profitable.
