i would like to invest my BTC,
so i was wondering if there is some kind of company/organisation/website, which lends money to people and takes money from investors. (both with interest)
BUT a well known site, which is Guaranteed no Ponzi and where the "partner" is the company/organisation/website so i can´t get scammed.
You should be able to know with certainty to investments in the bitcoin, because there are some sites that offer investment but the originals they are fraudsters. So, you might be better off investing in the exchange site that have been standing for a long time or on gambling sites that have a good reputation and have been standing more than 1 year. Because exchange and gambling sites is the most attractive investment spot and safest
