I don't recommend Nowpayments.io that belongs to a scam team behind Changelly, Changenow, and more scam projects for. a same team.

There are better and safer services to use so there is no convincing reasons with me to use nowpayments.io. Safety first and if we already know nowpayments.io was launched by a scam team, it is good to stay away from this possible scam. It does not worth to take risks and possibility of losing money.
