Ripple is shit, please do not invest at all. I expect ripple go to zero in value. They just against the decentralized cryptocurrencies mate. You have to understand the bitcoin price and ethereum alone if you are looking for the perfect speculation here.
I expect the ethereum to be settle the maximum value of 750 USD in the market.
Then litecoin may go upto 250 USD this time, may be after July you may find the better price in the market.
