To start trading, you must have a small amount of capital, it is used to buy Altcoins. The money does not need much because transactions can be started by buying cheap coins.
In my opinion, at least a small amount, which can help you own a reasonable portion of the coin you want to own, is important. At times, people on the forum show up with $5000 in hand. Yes this is now an amount that you can invest to own an ETH or two but back then when the prices were high, this was not the case. This means that this is an excellent time to invest because of the absence of that restriction that required a specific minimum amount of money to start.
Of course you still needed to have even a least amount of coin before you can start trading it's only basic, what would you use to trade if you don't have even a least right. So if you're going to enter the world of trading even if it is in real businesses you still need to brought out your coin doesn't matter how much it is.
