What about 10BTC investment? It generates 0.001BTC daily that is equal of $37 daily or 1200 USD monthly. It's more than enough income for those who live in poor countries and still a very good addition for those who live in rich western countries.
Not bad at all. Monthly money made from that can be easily used to cover up monthly bills in any under-developed country that has its local currency in red compared to the USD.
It can be a good method to hold those coins instead of keeping them locked in the wallet. Additionally the site allows you to withdraw the money any time you want. The only deterrent is the counterparty risk - meaning that you have to trust the opposite party in this case freebitco.in's owner and that they would not scam you, which we can all be sure that they would not.
That is easy math but have you calculated the risk of investing 10 BTC from the perspective of an under-developed country? I mean to get 10BTC in the first place is the biggest challenge for those peeps. If they get that much money then either it would come from a highly skilled job Or a business that has been up and running for many years. We are not talking about 1 BTC here we are talking about 10BTC which is not easy to come by just like that. If they get it then they could just save it in the local banks where interest is similar to freebitco or more than that.
However, if we are talking about freebitco and saving our BTC inhere then I can vouch for its guarantee. The business has been running generously for a decade I think so we are already in the safe hands. Plus look at the FUN staking, on going e=sport section money, Lambo contest prize money collection etc. It is definitely having good time with safe deposits.
