Today I went to a liquor store bitcoin atm and payed $45 and got $38.64 in bitcoin and I received it instantly but then it said "spending this balance will need significant Bitcoin network fees." And when I try sending it to buy altcoins it then says "insufficient funds." Then I saw that I can set to super economy but even then it cut my money in half. Bur then when I put custom it allowed me to put the sat/byte rate lower and it said "your fee is lower than recommended" but allowed me and was cheaper bur haven't confirmed it. What should I do?

Can I purchase a Amazon giftcard and convert it from Paybis? If I want to buy ripple, would buying Litecoin be the same as bitcoin for converting? Litecoin seems to take less money away than from bitcoin to convert.

I live in the US and I am thinking of investing a little money on cryptocurrency, I  want to purchase a prepaid card but I heard from some that you can't purchase it with it and others you can. I wanted to purchase Ripple and other cryptocurrency but is there a way you can recomend that I follow to purchase them?
