Just buy it and keep it as long as you can. You don't have to think about the maintenance fees, etc and i think the profit will also be higher 
Same here, I go for the buy if i have a lot of money, Only in this case, because i know that i will make a huge profit if i only invest in bitcoin itself. I mean that i buy a lot of bitcoin and keep them in my wallet. Maybe after that i will decide to buy some mining hardwares and start mining with this money.
