'OP' you may not know that no guarantee is required when purchasing bitcoins. Because Bitcoin is a virtual currency that all investors have confidence in. But while buying something no one will give so much guarantee that you can buy it at your own will. Bitcoin was at a point in the past when its value was so low that anyone was interested in buying Bitcoin. But even then people invested in Bitcoin without any guarantees. And now seeing the position of Bitcoin, people are more likely to buy it. Interested. And there is no risk in investing in Bitcoin. So no guarantee is required to buy bitcoins rather people invest on trust for a long time. Various pundits are promising that Bitcoin's future is bright and most people in the world are willing to buy a fraction of Bitcoin without any guarantees.
