RIOT, one of the few crypto plays available through NASDAQ. Options trading too.
Looking at the Martin trend, you can see RIOT turned bearish late last week following the news of Bitcoin/Tether fraud. (Old story)
Stoch and RSI both say buy but our momentum indicators say sell.
I bought some $5.50 and $5.00 RIOT puts last week that are already in the money. But it might not be a bad idea to snag some $5.50 calls expiring this week if they can be had cheap.
