I spent most of my time doing research on many altcoins, their old price to the present value and i find out that even if you sell your tokens today leaving few tokens worth few dollars for many years can worth something. For example if you left 9$ worth of bitcoin in your wallet since 2012 you would never have imagine what it will become today, in jan 2017 you can buy 5000 pieces of Ripple at 0.007$ which costs 35$ and in jan 2018 a XRP cost 3$ which turns 15000$, there are many examples like this on CMC, remember Tron too? My point is its bad selling off all your coins, if you needed money that bad always leave coins and tokens worth of few dollars left in your wallet just in case
This good but remember not all coins are worth holding for long term even if they are good coin; most coins that are launched on another blockchain as a start and migrated to their own blockchain always swap right? What will be the fate of someone who wished to hold for years but wasn't aware of swap. Am not arguing your points, they are valid but we need to be extremely careful of the coins we wish to hold for long term, let's always go for those that are solidly built.
