Work at a highly regulated financial firm, my employment agreement prohibits me from owning/mining any crypto, and must attest to that yearly (as well as reporting being a party of or to any legal action, etc). So with KYC in place for buying crypto, I am not going risking my job just save $40. Therefore I don’t and I have had good experiences with nexaph (credit card) amo/bfflist (paypal via alibaba) for kits of 10. and grey axis research (paypal), and an independent going by BioBombshell (venmo) for single vials, both seem to be reselling singles from group buys.
