My rule is to never put more than 200-250 SOL in a single wallet, but these are all HODL wallets. I never put more than like 10-20 SOL in an actively used wallet.

Also these levels all depend on your income and wealth.

And it’s not fill up one wallet then start another. If I have 500 SOL then I’d split them between 10 wallets, 50 SOL each. As I buy more, I fill each wallet in roughly equal quantities.

If I have 4000 SOL then I would do 20 wallets with 200 each.

It’s basically just, how much (in %) terms am I willing to lose at once. By using 10 wallets you limit your single wallet risk to ~10% of your entire portfolio.

The fees on Solana are so miniscule that you don’t even need to consider it.

I don’t understand your question.

It can be a lot of money. I’m a generalist software engineer and I still use varying tactics to mitigate risk (e.g. distribute tokens across many many wallets).

I hope not!

Lol it’s funny to be long term bullish (hodling a huge amount), but also short term bearish hoping that my buy target is hit. (Which is ultimately long term bullish b/c it’s just about stacking more). Don’t let perfectly good volatility go to waste!
