For those of you who have been mining for over 6 months, which strategy is better, get in early on a coin and hold for a couple of months or immediately pump and dump? If you have to balance between paying the bills and keeping some with hopes of a better payout, what strategy do you adopt?
How long have you held on to a coin? Do you mine several coins or stick to just one?

Thanks. I'm new to mining and would really appreciate feedback from people with experience.
