I have been using Coinmetro to buy some good amount of Bitcoin to invest in Minton Block 401k fund and each time the process has been fast and seamless. No hassles at all. Good user interface and responsive customer support. Definitely recommend! I needed to automate my passive income and hedge against the inevitable inflation. Returns are usually monthly or quarterly depending on investors' preferences. What’s more exciting is that investors also get timely and regular updates on potential 1000x project/coin picks in 2022 once signed up and subscribed. You can ask for Zach. He's one of their top investor relations managers. Thank me later.
