Anyone know where to trade options on small cap stocks (ie ones effected by crypto news!)

Steem peeps, I'm looking for some input. We've seen a lot of stocks move BIG on crypto integration news (ie accepting crypto, dealing with blockchain, etc). Here are a couple examples:

https://www.benzinga.com/media/cnbc/17/12/10930882/longfin-ceo-talks-stocks-huge-run-ziddu-coins-we-dont-deserve-this-market-
https://www.ccn.com/riot-blockchain-biotech-company-stock-surges-crypto-rebrand/
https://www.bloomberg.com/news/articles/2017-10-27/what-s-in-a-name-u-k-stock-surges-394-on-blockchain-rebrand

In the case of LONGFIN (LFIN) the CEO got on CNN and said they don't deserve the market cap, and after a brief dip it is still up big.
In the case of On-Line PLC (symbol LON: ONL), they jumped big on the announcement in Oct, but have continued to climb and are now about 3x greater than that first jump of about 5x. Similar story with Biotech company Bioptix Inc. (NASDAQ: BIOP), and RIOT.

Plenty of 'crypto portfolio equity pick' lists too like http://citywire.co.uk/money/david-kempton-four-blockchain-stocks-im-buying/a1076644

I want to trade options for some stocks as I'm already doing a bunch of research for my crypto portfolio, why not use that research edge to make some moves in my equities portfolio too? The problem is, Fidelity doesn't have options markets for these small cap stocks. I may still buy them and hold medium term, but would love options (I think a lot of these will see significant corrections pretty quickly ie 1-10 weeks as the market looks at their earnings and technology and sees they haven't really 'done' much yet). Anyone know of any brokerages that offer options markets for these small cap stocks? Or are they just too small for anyone to offer that?

Thanks!

PS if anyone has any opinions on these types of stocks let me know!
