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.
To invest 10 BTCs in an online platform without any further assurances over the money is really a big risk that most people wouldn't take, especially because there are many other alternatives of investments for investors with such large sums of money under their disposal. However, we are probably considering 10 BTCs is equal to the total sum of money this person has, but let's imagine 10 BTCs represented only a minor portion of his total patrimony, which totalizes in 100 BTCs or more... Then I think it's perfectly fine to risk 10 BTCs in freebitco.in, because that is an amount of money he can afford to lose without major negative consequences for his finances.
It's a decision based on calculated risk which may also have further sentimental meaning for the investor. At least, for me it would have, considering the so many years I've been accessing this platform frequently.
