regulated custody solutions that combine institutional-grade security
first - regulated custody solutions are not for Bitcoin - that is screaming fiat
. Bitcoin was designed to escape the need to trust a 3rd party with your funds. and there is no security in any custody "solution" nearly ever custody solution at one point or another gets "hacked" - more or less they leak their own data for probable payment.
Never trust any custody solution with anything you are not willing to simply write off.
