I have been reading about exchanging sites. all of them have people who lost their money due to hacks, or investors got their accounts closed, frozen (Coindesk) without proper explanations, usually exchange sites let them deposit money, but they don't let them withdraw their money.
Kraken(some review sites list this is as one of the best exchange site, what a joke) is also a shit hole, the same thing, money and coins missing, buggy laggy website, no customer support.
How do you make money of cryptocurrency when the exchange sites are predators to hunt people's money? Decentralized trade sites maybe? If I read positive reviews about these centralized exchange sites , they doesn't seem genuine at all, most of the time, it looks like someone ordered them from Fiverr. Binance, Bitfinex with the Tether fiasco, Coinmama.... All of them looks like scummy attempt to get your money.
Some investors on exchanger sites lose their money maybe because some are just pretending they were traders without any knowledge about trading or they didn't research or make a study about the coin they are trading off.
You can earn crypto currency that can be exchange to local fiat by joining signature campaigns, bounties and other job online that will pay you BTC or other crypto currency.
