It seems coinbase is not able to learn from its past technical problem and keep repeating .On 2nd of June when bitcoin price was hike because bull run and the market cap started growing but all of sudden , $8 billion worth company coinbase again as per usual ,was down which resulted many traders could not do any transactions and trade through out that time period and we noticed market suddenly crashed and bitcoin went back to $ 9500 from 10k above.

The question is why coinbase is doing all these and why every time all the users has to be victim of their problem?

I am observing coinbase since 2012 and what i found :

1.  whenever there is golden opportunity of arbitrage at different market and you can not transfer your bitcoin or ETH quickly as message pop up like 'Network is highly congested and all the transaction will take minimum 12 hours time' 

2. whenever there is bull run  in bitcoin then either coinbase server down or the site is bugged which makes completely annoyed .

Coinbase must know that there are many good rivalry like Binance , Gemini and now crypto.com whose service standard is absolutely amazing and affordable with lots of promotional offer then why because of all these technical problem ,it spoiling themselves the reputation of such well established company in cryptocurrency . 

if we go to twitter there are thousand of users asking same question and it is 'why' .

people now loosing faith on coinbase credibility and predicting unusually that it will never improve and keep doing it . Hope coinbase will sort out these issues soon or will keep loosing its users forever .
