Profit is Profit, either big or small.
Excellent, the best way to invest in always 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. However, 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.
