I can advise you to invest in Tomochain - Electrify Asia - NKN - Phantasma and Beazant.
These are my holding i am holding and buying these altcoins. I love tomo because tomo will have masternodes and tomo will have their own blockchain also their mainet will be ready in December.
Beazant already listed in bithumb and their team is solid. NKN and EA also very solid projects.
