There are lots of companies out there trying to create the next big cryptocurrency but what will determine who stays and who will disappear? This is simple.

Getting people to actually USE your coin is what determines who stays and who goes. Those that can make themselves relevant will, of course, get the action. Getting listed on an exchange will go a long way towards proving to the people that your currency is something worth considering.

Don't be fooled by every Tom, Dick, or Harry who tell you that their coin will be the next biggest thing or will even replace Bitcoin. Believe me - there are many out there who are proclaiming this. Do your due diligence.

The only way that I know that a coinmaker will actually survive the long-term is if the program is making themselves popular in other aspects of the online world - companies like FutureNet. Companies that allow you to share in profits with them in various online portals. Only THEN will I feel comfortable thinking that other coins can't just come along and make what I'm already doing (buying and using these coins) irrelevant.
