What is the best site for this in the UK?
I am only going to start with $200 roughly to see what I can turn it into over the next few weeks and months as the market is starting to get very volatile so could be good opportunity to make some extra money which would then mean I can invest more into my long term plays.
You didn't mention what altcoins you are referring to, dude. What exactly are they? Most of them are altcoins because they can give a profit to any of us here in the crypto space. And if 200 dollars is the beginning of trading that you will turn into capital, that is actually big for me.
That's why I just don't know if you know anything about trading, do you? because if you don't have it, it's better that you know something about it so that your money doesn't go to waste. It's still important that you have a real understanding of this, rather than the fact that we'll just be confused or rely on luck because it's not the same as gambling.
