In my opinion, the good Altcoin that investors buy now is that the Altcoin has good potential and its price is low. They are NEO, ETH, LTC, EOS, XLM ... Buying mushrooms and keeping them is a profitable decision for investors.
Would not buy NEO. They failed on delivering. They are still at 33 tps second. Neo wants to be enterprise ready in 2 years time. Stratis is in 2.5 months enterprise ready. Can handle over 50k+ tps. Already have some enterprises adopting its platform. Next week more information on the relationship with Microsoft. With the product launch in 2.5 months time expect more enterprise announcements who are holding ico's on Stratis platform.
