i think blockchain is everything for bitcoins any ways we have to buy now because in future its seems the price will rise for sure. you can't say we can buy now or then. maybe in future price goes down
Its good to save bitcoin and hold it in few weeks or months the price is flactuating and its a good investment for me because if you sell it when the value is high you will surely earn but currently i dont think its wise to buy now, as you can see the price is a bit high just wait for it to drop again then start to save.
You have not so high rank, so I suppose you are here only about a year. And you probably don't know what happen in 2013 year. The price were 1000+$ and in one moment it's just dropped to 150$ man! I think now is not so good time to buy bitcoins. The price is circling and I expect some new fall in the nearly future. Buy bitcoins when the price is low - that is the law.
