Ok then any other way to increase my cryptoearning except forex trading
There aren't many. You can deposit BTCs at FreeBitco.in site and earn passive income (0.01% daily) or you can save a decent amount of satoshis and invest in Crypto Casinos. Some of them allow few AltCoins too, like LTC for an example. In this case there isn't a fixed return rate and as we are talking about an online investment, there is always some risk involved... Be aware about it.
