That's where altcoins are useful.
Bitcoin was supposed to be useful too. Now it has been rendered nothing more than a Ponzi scheme. It has no real purpose other than for more and more people to come one after another to give money to the guys already in. Then BAM!!! a total freefall collapse. Well sometimes i got the same feeling.....
But it would be unwise to say it a Ponzi. It doesn't fall in its definition.
