Many options are very illiquid
I can name bundle of them where you buy on market, it will shoot up hundreds of %
or there are not even sellers
patience is the key to accumulate options if you think the stock is going to run
nobody will buy on significant market premium unless he/she is a fool
I remember seeing CSDO trading down to 0.2c
sell order was 1-2c
only fool will buy up to 2c
