You should focus on Neo because it can bring big profit. Neo is going to legit in China, it really good news.
I got back into NEO a little and got 80 NEO at nearly height of last pump $40. With China allowing ICO again soon but only allowing NEO based ones its price could serious pump.
It is possible that NEO could pump again, but don't blindly fall for the sly tactics used by the Chinese government to manipulate the crypto market like last time. NEO has a lot of potential, but it will reach its new ATH only after a couple of years according to me and Ethereum would have a big role to play in this scenario. Coming to the question posted by op, I think he should sell 70% of his holdings for some awesome profit and HODL the rest for future profits in the long run.
