Excellent, the best way to invest in altcoins is taking out capital when in profit and leave the profit to run. This works for decent projects, at least a project you have some level of believe that the team is cool, developmental progress is ok and a strong community supporting it.
That is right but I always consider the profit you made should now be treated as bankroll or capital itself instead of looking at it as profit and taking unwanted risks. I agree though with decent and known projects you can do this but really profits are part of your capital the moment you earned them and must be treated the same way.
for projects with just hype and no serious development, it's good to take out capital plus profit no matter how little the profit is when necessary. Greed kills, this is a norm in crypto. I had the opportunity to make good profit from PAZZI but I got drowned due to greed. I learnt that lesson the hard way never to be greedy with any altcoin.
But if you know a project is all hype and has no development why would you invest in it first of all and then if somehow you invest and able to make profits then really just take whatever the profit is, agreed on that part but finding which project is all hype is difficult.
