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.

Some good reasons why you use bitcoin.

1. It is fast. Transactions are instantaneous and confirmation times are usually done withing 10 minutes.
2. It is cheap to transfer any amount of money anywhere. Fees are insignificant at this point.
3. Your bitcoin are your alone, they can't be blocked by bank, IRS or any institutions.
4. There are no charge backs.

Yes, There's still a lot of people who are against or do not believe in bitcoin and what I think of is - it is because of the risk of security. I even tried to discuss this with my friends at work and they do not believe that they can earn money in bitcoin even without any investment.
