My suggestion is that you invest Bitcoins, they are far more reliable than other cryptocurrencies, make sure you also trade with Paxful because they are safer to use.
The first time I learned about a bitcoin is thru my friend (He is successful now) he told me how it will bloom, then I tried to study it for 2-3 months, watching youtube clips on how to buy/sell Bitcoins, learn how trades work, learn the market, goods etc... I then purchased $25.00 worth of bitcoin by using an Itunes gift card (because I feel safe not giving my information)
I have been using Paxful for the last 3 months now and I raised my coins selling and buying them.
You can, fortunately, buy and sell them for services, You can have it sent thru PayPal or trade them for cash thru Moneygram. I mainly use is Paxful for trading, they are the only marketplace that has 300+ payment options.
