This is why is important to have some of the funds in cash, and buying those dips, meaning those dips are an opportunity for profits. The only real problem for this network is when more than 50% of people leave in one day. But I don't think that is something that should worry us at the beginning of funding this network.
Again your piece of the pie is always the same, HOLDING is what makes profits in the market or buying the dip, with more capital we can set bigger and better buy/sell positions in the long term.
I understand now, so it just looks like this is actually very viable, especially if the owners/administrators of the network was smart enough to do this and keep enough cash and money on hand, maybe a certain percentage of the monthly fee you put in should be not added to the network, and sent to a wallet to cover the dips of the market?
I don't think more than 50% of the network would exit, you can always put a limit, for example, only 10 percent of the network is able to leave in a day, so this will keep you and your investors protected.
