The profits obtained will not last long if people continue to join, because the number of people there increases while the stock remains so, there will be a reduction in the prize portion.
especially if suddenly the results drop because the number of people continues to increase.
Well in my own opinion I think there is a benefit to join mining pool in their early stage, reason is because if you start from the day one I think before people will think of joining the mining pool I'm pretty sure you must have make alot of profit either.
Indeed, that way you can get more benefits than others. because the earlier, the prizes are still bigger than if many people had joined as miners.
but because this is a new coin, don't hold it for too long. because the longer it takes, and the more miners there are, the more prices will fall. unless the coin has a solid community or token holders.
