I have dedicated $5,000.00 to invest in BTC or other alt coins. Thus far I am the proud owner of the following:

1. 2.01 LTC which I paid $25 a piece for years ago
2. 75 FTC which are worthless
3. .15 Ethereum that I secured off an $80 mining contract


I am looking to purchase Ethereum, Ripple and other strong alt coins. My questions is, what is the best way to get the most for my money? Mining contracts? eBay?
