The volume doesn't matter much. You can buy on the the ask and sell on the bid and you can usually see the number of contracts available on both sides. Obviously the if the bid/ask spread iss too large, more than 10 cents for ones with a lot of open interest you can put in a bid 5 cents under the ask and see if yo can get filled.. You also need to have a good idea how options work and trade. I have some May 2.50's expiring in 2 days so I need a good pop tomorrow or they expire worthless. Also have some Aug $3's. The truth is though we're talking a very volatile $2.50 stock so it may not be worth the risk to play options and possibly lose everything if the timing isn't right when you can get a good profit if the stock runs up without the added risk of the time limit. I will say I expect Q2 to be a big quarter so if you can get them cheap those Aug calls may be attractive and as I said I own some.
