Today price of bitcoin is 3800 dollars so if you want to buy bitcoin now you can do itm but invest only you can afford to lose . Bitcoin is good for longterm and for sure if you hold bitcoin for few years you can earn a lot of profit because maybe next month the price become 5k dollars and it will continue to increase again. You can store your bitcoin in coinbase they base on Us dolllars and this wallet is very safe.
Coinbase has major security issues. Trading is difficult enough. Hackers stealing your Bitcoins on a daily basis is too much for me.
I have just finished reading the article in Fortune.com (Hacking Coinbase: The Great Bitcoin Bank Robbery)
http://fortune.com/2017/08/22/bitcoin-coinbase-hack/Coinbase was successfully hacked 30 times in a month. That is an average of once a day.
i have been Googling Coinbase. They are having appalling reviews about not paying customers, blocking access to their accounts, and not responding at all to emails or phone calls etc.
Some customers are saying that any big deposits are blocked from withdrawals and then the customers are blocked from accessing their accounts.
No Coinbase for me
