You have not understood the fundamental : buy the rumours, sell the news. You did the whole inverse it seems. What I would do would wait for a very big ICO, the one you are sure of its success like ZrCoin or EOS. Just buy and wait then.
If you do not like ICOs, buy Ethereum in a dip, and sell at 0,5% profit, repeat, again and again. Start keeping the profits in ETH, as this is for me a crypto-currency which has a great future !
Is it not what I'm doing? I'm buying coins which have important news coming up and when the news or the update comes out, I sell them. Can you suggest me where I'm wrong? Thanks
