There are a few common keyword in the .com and .net lists: bit, block, chain, houston, harvey.
My experience shows that only 2 or 3 thousand domain registrations are enough to bring a keyword into the top 10.

Top 10 Keyword Registration Trends for .COM and .NET in August 2017:
*These are not the top 10 keywords overall but rather the keywords that saw the highest increase in terms of domain name registrations in the past month. Each list was developed by examining keyword registration growth relative to the preceding month, such that those keywords with the highest percentage of registration growth are being reported on. This method is used to eliminate commonly registered keywords, such as “online” and “shop,” to provide a true look at monthly trends.
