Why are crypto currency popular all of a sudden?

Two factors.
1. Because of its decentralisednature.
2. Because of the bubble effect.

Because there is alot of money to earn with this crypto currency its like gambling

i would say go with penny crypto/airdrop since they cost less than other famous crypto and hodl them for about 3 or more years then see the magic, i'm not saying to hodl only one crypto/airdop hold many as possible

Like it was said befor, the early investor made alot of money out of it, its gonna die soon tho since everyone does it.

I"ve Invested in litecoin and it dropped like a rock meh i tried atleast i only invested what i was willing to lose.

You think that this happened fast? I think it really took a while. I think they are becoming more popular because there are more and more payment solutions with btc

Bitcoin is a revolution. so is blockchain. I think its not a hype, because i have not seen someone yet, who suddenly stopped using bitcoin. The adoption rate among the civilization is just increasing in different speed. sometimes booming sometimes steadily. its all about the consensus and revolution for our society. other crypto projects have even increased the value by altering the mechanisms of blockchain. This allows more use cases and applications. Market is going up for sure. The next big whale pump will sky rocket our lives through the roof to the lambo on the moon.

It's the bitcoin boom. Read an article I read about it and everything made sense. How it is being used, and how it could come and affect us in the near future
