The coins to HODL are the ones with solid tech, an active dev team and a motivated community. One such coin is XSPEC; it is a solid privacy coin that is currently a steal at less than $5. Privacy coins with solid tech are especially desirable for HODLing, as the demand for them will skyrocket as governments increasingly try to surveil, tax, and control anything crypto related. When evaluating a privacy coin for long term investment, make sure its tech delivers both network privacy (protection against IP surveillance) as well as transactional anonymity (protection against blockchain analysis).
I hear there are
some Altcoins that are profitable now. Among others are XRB, XRB or Raiblocks are Altcoin which had appeared and became popular because of how to get it fairly easy. You are only required to fill captcha and can get a number of XRB that time the price is still cheap. However, the current
price of XRB so multiply to many. It is very profitable for the XRB holders. There is also XRP, many people say that this coin is profitable. There is another NXT. I do not really know about this Altcoin, but I hope
you find out for yourself about the Altcoins I mentioned above.
