lending bitcoin is safe grow your bitcoin
In the past lending bitcoins could be a great service, and almost a no risk way to grow bitcoins, nowadays there is a big problem, thats the most people are asking for loans and dumping their accounts. There is always a risk to invest into any project, till the moment there isnt a place where you can let your coins and be sure you will get more bitcoins.
Lending is never safe way for growing bitcoins. How can you be sure that someone will return you bitcoins you previously gave? With so many scammers, that know how to make fake ID`s, diplomas, fake works, in my opinion there is no safe collateral, except you can see it with your own eyes and check on different ways depending from what kind of collateral is in question.
Lending to companies that invest later in some projects is also very risky, I know for many cases where this companies turn out to be just ponzi schemes. Choosing right one is not easy part, maybe is better to save bitcoins like I do, they will worth one day a lot, price is going up that is a positive thing for us holders.
