didn't know you could even go that high, aren't there limits? What is the most you could lose accourding to the rules?

Flint is okay. What I personally don't like are the PIN protection, the too short wallet names, the ADA exchange rate graph on the front page (I don't trade much and care only from time to time, it also seems to be USD only, I'd need EUR), the decision if it thinks something is a token or a collectible/NFT. Also, it seems to think that my wallet is not delegated, although it definitely is (Flint even shows the rewards).

there are no limits
