Don't worry, dude, that's why they're called CRYPTOcurrencies. You can just use the Internet and buy them from people with cash or just justify the bank transfers with other business. Cryptocurrencies are completely anonymous and secure, so you will surely have great opportunities coming for you if you invest in them. In fact, in Venezuela, my country of origin, the crypto world is greater than ever. I don't think the crypto scene is bigger in any other Latin American country. Since the government is blocking all our trading opportunities and trying to stop us from getting foreign currencies, people all over the place are using cryptocurrencies more and more to escape these regulations. They will never win since crypto is decentralized, private and encrypted.
