I know a lot of people have different reason why the love and embrace bitcoin.
For me the decentralized nature of bitcoin and the thought of being able to send coins to anybody in any part of the word, no third party, no regulation(specific amount), no bullshit is mind blowing.
Yeah it is being able to send anywhere in the world with no amount limitations and documents needed. You just need an address and then after 10 minutes or more depending on the fees. It will arrived to the person you sent it to. You don't need a verification, swift codes, phone numbers or anything to prove your identity. It's pretty amazing. It's ability to grow in value in just a short amount of time is also one of the things that amazed me because I don't know any other investments that would become 5x its value in just a year.
