Thoughts on keeping meme coins on exchanges

So lately we have all seen how important is to have coins in self custody. And I agree with that.

But I did notice something. 2 times so far when Elon did something connecting Twitter and Dogecoin, DOGE pumped. And I had my DOGE in a hardware wallet tucked away somewhere inconvenient so I prevent myself from impulse selling stuff. I could sell at the spike, there was quite a low chance that the price will remain there. But it would take some time to get my Ledger and send it to exchange and sell it.

So I didn't do it because I am a miserable hodler (with the exception mentioned in my other post).

I realised something. If you own a memecoin, it might be actually smart to keep memecoins such as SHIB and DOGE on exchange in order to react to those ridiculus spikes. At least to take advantage, sell and maybe later buy more at lower price, ergo accumulating said coin.

So you wanna say: "What if the exchange goes to shit and I lose my funds?"

First of all: You have to be a special degenerate and gambler to have a high percentage of your portfolio in memecoins.

Second: If you do have a large amount in meme coins, that would mostly mean you also have a lot of money already to be playing around with it like that so I guess a potential loss like that wouldnt change your life for the worse.l

So tell me if I missed something important here?
