How much would you make as first amount? I was thinking £50 bit even if this times by even 10 that's only 500.
Would 300 be a more realistic start
It all depends on how much you can afford to spend. Start small, and when you study the market of Crypto-currency, you will increase the amount of the deposit. Do not worry if the course falls. You have not lost anything until you have sold it for less than you bought it.
