Ofcourse Bitcoin. One reason to buy bitcoins are a valuable asset is that only 21 million of them will ever come into the world—and most of them are already here. As those familiar with bitcoin know, the number of coins created by the mining process drops by half every few years. Right now, around 80% of all bitcoins are already mined and no new ones will appear after the year 2040. This scarcity could continue to drive up demand.
