my best friend told me about bitcoin when i need money, i started with trading , my friend told me that can make your money double, but just like you, i invest in exchange and bought bitcoin and then all came into a correction. I hope bitcoin can reach new ATH again
You can start by investing in exchanges like Bittrex, Binance or other, while trading you can find out more information about the coins but I think you should also join in bounty and airdrop to get additional profit
