Is there any data on NEO's adoption rate? How many wallets do exist? Is there any data about the growth of NEO's adoption?
There is a lot of good information here
https://www.reddit.com/r/NEO/. It has an extensive list of wallets, resources and other stuff that might be of interest.
If you base your NEO investment purely on the size of the reddit community, it surpasses EOS, ADA, TRX, & NEM...it's number 2 to ETH...Price wise based on the community ratio of ETH to NEO, NEO should be way higher.
Whether this is a good metric to go by is completely your own opinion.
Community makes up a large portion of BTC's value.
