I tried NEXO small scale with EUR and was very happy. However they are quite opaque with the whole "$100M insured" thing and I am not sure which situations the insure governs and is the amount for the whole platform or your own account only? I think this part is easily misunderstood.
Also there has been discussion in situations where you deposit your crypto and in some case, the platform has the right to "purchase" your crypto off for the market price. I personally think this is a bit far fetched to have any real backfiring effects but one thing to consider.
I still think there's something opaque in the platform, but it has been running for some solid years now and it seems very reliable. Time will tell what could happen during very major volatility in the market or big swings in people withdrawing/depositing. But after said that I couldn't say it's more riskier than the banks are.
