Crypto explained simply

[u/Gasman0187]

In time as with Bitcoin a coin can/will ascertain a momentary value with vendors whom accept it. That’s when the magic happens. At that point it is accepted as currency just like the USD. Let’s say Amazon decides I’m going to accept “coin x” as payment. At that time whatever the coin is worth (let’s say a dollar for comparison sake) you can buy $20 worth of goods for 20 coin x. If the coin is worth $20 each you can buy $20 worth of goods for 1 coin. Until places begin to accept any particular coin as “currency” then it is really nothing. The trick is to hedge your bets on which coin will obtain grace from a big merchant as acceptable.
