Hello again....since i want to know what is bitcoin for you...and what you think about anothers cryptocurrencies like ethereum,litecoin,dogecoin,eth classic,zcash,dashcoin,monero,golem and others...
That's why cryptocurrency is really hot right now. Not anyone can afford to buy Bitcoin then they have to look for other potential coins that have many features and use cases that Bitcoin doesn't have. Investing in altcoin is also interesting.
