I plan to hold for 2-3 years at least. Thoughts on potential, predictions, and if I should be consolidating any coins?
From your portfolio, most stable for 1y+ will be BTC, XRP, ETH and NEO because of their usage or smart contract features.
The rest could make it 2y+ or could fail. Most are still just tokens.
