I have seen many hate on cryptocurrency , many have had huge losses but myself, involving more and more into the space, I see it as having major advantage in terms of investing as well as a breakthrough technology.
Pros i can think of:
Eg :
let say you hold Bitcoin in your wallet. Its inaccessible by banks , or government or any other person besides you . It like holding cash but online. it cant be frozen or paused and can be taken anywhere in the world. You can access it in the remote part of the world with an internet without associating with any bank or country.
Smart contracts like Ethereum can progress transactional capabilities. I will receive the service provided in the contract without any intervention from anyone . Auctions can be fair, financial raising can be transparent ,lotteries ,betting ,etc
Nfts can extend to real estates ,music etc and prove real ownership
The financial lending /borrowing space is solid.
Well since the services are not geographically limited it promotes the concept of globalisation more.
Cons :
Volatility in price
Hard to regulate
Pro tip: whenever you place a BUY order - ensure to yell TO THE MOON!
