The recent Dash trend in price, has made me a good amount of profit, so I have benefited from holding it. Nevertheless, if only there was a way to get rid of coins which don't have market support or active development, then it would be great. But up until now, I guess that it would be up to baghold those altcoins. Just my thoughts. 
It's unbelieveable, isn't it? Usually I only follow the trending coins, not hodling much. The topdown ten of the coinmarketcap are probably there for a longer time period.On Dash you need a critical amount to participate in the Masternodes game. This is either a good example of customer conversion or a bad one because newbies no more get triggered to engage there. Entry barrier can kill a coin.
