Its good to invest to several coins not on a single one Top 20 Altcoins are good , as for me im trading and investing to ICO because there are a lot of promising ICO right now that for sure will grow over the years like WPP Energy a platform that operates on energy sector that offers renewable energy that will reduce the carbon emission in our ecosystem and also to enable access electricity specially in remote areas with lower cost and more efficient compare to Power plant energy sources !
