What is your goal?

1. Short-term profits: gambling or P&D?
2. Long-term profits?
3. Ideological investment to support crypto-currency adoption?

Answers:

1. Close your eyes and pick some from a grab brag or get on the inside with a good scammer with a good technobabble story.
2. Bitcoin (maybe Monero, but I would prefer Bitcoin yet Monero has greater potential long-term upside)
3. IMO and AFAICS, no realistic choice yet available, other than Bitcoin ecosystem investments
