Anyone here to explain me the concept of doubler sites? Everyone says the doubler sites live from our deposits. But the money that we deposit we get back (normally) plus profit so the site make minus (normally).
Your investment pays other peoples profit, you get paid by other peoples investments. This implies an exponential growth of investments which in reality can only be unsustainable. Such a system will collapse eventually, especially if there are promises like "doubling in 96 hours". Some people will loose money, it is that simple. Usually the site owner runs with the remaining pot at some point, but that is not necessarily the case, some just pay out themselves a percentage of every investment and there is no remaining pot.
You can see it as gambling, you bet on the time of collapse happening after you made your profit. But if you do so, you should also see that the "house edge" of such sites are not transparent.
I know one doubler that exists for a for longer time (see signature), the admin claims not to use other peoples investments for paying you and he also did not promise any specific time for doubling (in reality it has been 2-3 months, usually). This has proven to be more sustainable, but one can still not know if it will collapse at some point. It remains risky and needs a bit more patience, but I am happy with the profits so far.
By the way, I am surprised that bitcoins.work is still up and running. It is you (the investors) who keep it alive.
