There are a lot of ways to increase the capital of the cryptocurrencies that you have. One of those ways is through trading the coins but you have to be careful because just as much as you stand to make a lot of money from it, you also stand to lose a lot of money from trading. Another way is for you to buy the coins at a cheap price, wait for the price to go up and then sell for a lot of profit which you can then reinvest and get even more coins from it.
