I hold Steem and Steem price can be gamed but Steem also can be locked up. Same is true with Tezos which has a very similar DPOS consensus. The reason to hold for the long term is if you think the crypto is undervalued. If you see the prices of these cryptos going up within the next year or next 5 years then selling it means you take on opportunity cost. There isn't going to be any interest in holding fiat, and stocks are in a bubble. Real estate is good if you have millions of dollars but you take a risk with that too because that can collapse.

So the options are over priced stocks, a real estate market which could collapse if there is a recession, or cryptos. What do you know of which has as much potential for growth and which pays interest?
