I have, let's say, 50k to 100k sats and I keep them on a hot custodial wallet (like muun, wallet of Satoshi, blink and so on). Now, I'm aware that these wallets are custodial, which means that I have no control over my sats, because I'm not the owner of their keys. But what other options do I have for this amount of sats, in order to make them more secure?
What would you suggest a beginner do?
I have also heard of cold wallets, but, let's just say I have never used one. Given the fact that I only have 50k to 100k sats, is it worth investing in one of these cold wallets? Or should I keep these sats in custodial wallets until I accumulate a significant amount of sats and then put them in a cold wallet?
