In today's turbulent world, people must learn to decentralize their income and ways of earning as well as storing and transferring it.
Cryptocurrency is ideal for storage and transfer. I just installed a wallet on my computer and buy coins on exchanges, but keep them in my wallet, this will further secure your savings.
For extra income you can use trading, forex, poker, sports betting and more. Remember, you have to learn all these things if you want to have a chance to have this income. I, for example, have been betting on sports for a very long time, even have my own website [https://paribet.in/](https://paribet.in/) about betting to help beginners and more. Good luck .
