The easiest thing is to start cloud mining.. The advantage is you pay a one time fee based on how much mining power you want and what coin you want to mine.. and it will mine for you for as long as mining that coin is still profitable.   I like genesis mining because the allow you to move your purchased mining power around from coin to coin or even split it amongst coins.
