Besides the obvious ones like ETH,XMR,EOS, i`m planning to aim for lower altcoins. The one that i have in mind might not be top 100 but its on the right path to be until the end of the year. You can do some reasearch on MWAT (Restart Energy Democracy). They already have the revenues to get big and also with their plan of expanding in the next couple of years, it`s gonna be a blast. The project/staff members already have experience in the energy field and the ICO was completed ahead of the schedule.
