Bitcoin is one of the best investment in the world right now and the best crypto coin, Bitcoin has made a lot of people rich and has helped grow the economy of the world, Bitcoin is the first crypto coin to be created and has done well in it's growth, some people thought Bitcoin won't go this far that was why they were not interested in Bitcoin, 10 years ago a lot of people had the opportunity to invest in Bitcoin but refused and today they are deeply regretting there action, Bitcoin has a great future and is not late for anyone to start accumulating Bitcoin, some people feels investing in Bitcoin is late now and one can't make any gain from it anymore but that's not true if you start accumulating Bitcoin and holding it in the next 6 to 8 years you will make a huge profit.
Some people also feels the price of Bitcoin is too big for them to start buying but Bitcoin is divided into small units and one can buy Bitcoin worth $1 and that is one good thing about Bitcoin anyone can get involved with the little they have.
Bitcoin will hit $100k soon, people believe is impossible for Bitcoin to it $100k and that is why they are not investing on Bitcoin, but same way those people who had the opportunity to invest on Bitcoin 10 years ago is same way people who are doubting Bitcoin reaching $100k will regret very soon.
People who will doubt Bitcoin hitting $100k is those that don't know the history of Bitcoin growth because if you know the history of Bitcoin and it's growth you will never doubt.
