Strike is finally live in Europe (Thanks @jack mallers). KYC-needed, unfortunately, but very smooth and fast. Topping up with EUR took seconds from my bank. Strike seem to be incorporated in Poland but their bank is in Luxembourg. Fees are 1.29% up to 1.000 EUR monthly, 1,09% up to 5.000 EUR. 0.89% up to 50.0000 EUR and then 0.79% above. If you do a conversion above the levels, you get the bigger rate (eg. if first conversion is 2.000 EUR, you get 1,09% for full amount). If you want to try from Europe, use referral https://invite.strike.me/AEIQEX to get 5 EUR. I'll get the same.
