Its all-time high is far from the price that we're looking at today.
Should I get rid of my HYC for what little there is left of the investment (with a loss) or buy more?
I wouldn't buy anymore. But if you have that choice to sell it and buy something else, this is what I'm going to do. I'll sell it for bitcoin.
Good choice for bitcoin, but also think about with other alt like xrp or trx because that's also a sustainable asset nowadays. The potential of those coins will be great, based on the trend it has in several trading site particular with binance and other following exchanges.
