Compounding your bitcoin returns through P2P crypto-lending platforms is one way to go, but if you're considering a long term holding, you should look at a handful of select token sales and invest moderately in them. Perhaps 10% of your total investment, say. And be prepared to hold on to your tokens for at least 5 years. I imagine it will take at least as long as that to make your BTC (or ETH since so many of the promising ones run on that platform) investment do justice to their returns, especially considering the massive surges you see in these currencies at present. My prime picks right now would be:
- IOTA (not an ICO, but still a promising utility coin)
- Nucleus.Vision
- Leverj
- Monera
But don't take my word for it. Do your own research and figure out what looks good to you. This list is simply indicative of ICOs that have done the groundwork, have sound technology, extremely feasible ideas and solid investment backing.
