I believe you wanted to say "trusted wallet", not your keys not your coins! Platforms can collapse, so never hold big amounts there, FTX is not the first big exchange that went down the drain.

The winning strategy is investing in Bitcoin and holding it, the longer the better! I think some other coins are also great for long-term holding, we can underestimate the success of Ethereum, BNB, and some other great coins. We all know that these top coins (and some others for sure) have huge potential, so investing and holding them can pay out a lot one day, especially if we invest in them in these bearish periods.
