2 reasons, DeFi and blockchain.
DeFi is Decentralized Finance and blockchain is security.
So imagine a currency not owned by a countries governing banking system, so no one central entity has any control… that is Decentralized Finace. It is not subject to any governing bodies control.
Blockchain is how Crypto tires to, and mostly succeeds, in being 100% secure. Loses have actually come from websites hacks more than people breaking into the blockchain system. It essentially ensures if a crypto piece of currency belongs to you then that is the end of the story, your the recorded owner until you sell…
Then all the computers in the network have to relocate that crypto in the whole blockchain, not just the node you updated when you made the trade on your desktop but now everywhere else in the world where a record of that crypto is held.
And this means there is no ‘house bookie’ or stock exchange to tweek the outcome in the way.
So not only can you now gamble for fun and be in with a genuine chance of not being taken for a gump.
With DeFi the central controlling government can’t pass a law to deflate the currency on the international market. Or untie it from the gold standard by law, for example. As there is no central governing body at all. Every crypto available is immediately available in over 90% of the world.
Plus it avoid all the back room back slapping that goes on with stock exchanges and IPOs which occur out of the public eye all the time.
It truly is a chance for the little man to play with the big boys on more even terms than has ever been possible before.
Plus if you look at the market cap values and realize that money is only and idea back by confidence then having a little fun investing in crypto is a wise move.
