please use fiat in buying such and keep your precious BTC and ETH from the bankers.
can you explian why? I don't really understand the difference between buy with FIAT and BTC/ETH ~
Buying them using fiat money instead of your precious BTC and ETH keeps your precious Crypto away from these bankers. I personally use my USDT hedges to buy XRP(they are both shady if you didn't know). Once you don't and they dump all the XRP on the market, and they will hold a lot of the BTC and ETH on circulation, that will make the price of BTC reach higher highs and your XRP pegged on the dollar.
In summary, when you load fiat to buy crypto, use your gains to buy XRP and keep your BTC and ETH safe in your wallet. Just ride the wave.
