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.
the thing that impresses me regarding bitcoin is its volatility, you could take advantage of the price since it's price change from time to time. its security is also impressive you'll never get yourself a doubt in investing on it.
