I have the level 3 verification on my personal bankera account. It took like 2 weeks and a few emails sent with docs and everything to get approved but never had a problem in 6 months since I got my account with them. Even after all the KYC and documents sent to them there are some "operational limits" like 10.000 EUR / transaction ; 25.000︀ EUR / day and 50.000 EUR / month for personal account. But you can increase︁ this limits with a request. If you have some docs to backup your cash or︂ crypto, you can work with much larger sums without a problem.
As for CRS-reporting, I︃ don't think they do it, EMI's are not forced to report through CRS, maybe if︄ there is a request they will collaborate without hesitation. WISE said that they don't report︅ anything for now. Things can change quickly so do it at your own risk.
