You should stop trading for the time being - your description sounds like emotional and irrational trading that is causing you to lose Bitcoin.  You need to have a good understanding of the cryptocoin industry, the right mindset, the ability to assume risk, and patience to trade successfully.  Also, what is a 40% loss one day in the world of cryptotrading, may not be the next day or week.   

I successfully trade stocks and cryptocoins, so much so that I am able to live off of my earnings.  I would say that trading cryptocoins is definitely more difficult to trade than regular stocks because companies on reputable stock exchanges (NYSE, NASDAQ, LSE, etc.) are mandated to provide a significant amount of information to the public which makes it easier to predict stock behavior - this is not the case with companies that go ICO.  But cryptocoin trading, when done right, can certainly lead to larger profits than the traditional stock market.  You must note though, the coin market and stock market do not behave the same. 

I personally measure my stock trading success by percentage and dollar value of my portfolio.  I measure my crypto trading by the Bitcoin value of my portfolio.  Use common sense, start out small, and know your chosen industry well.   
 

It depends what you're doing with your coins.  I keep a couple of wallets and also a large chunk on a what I feel is a safe exchange because I am constantly trading the money that I keep in the exchange.  I use the wallets (online, paper, and hard) more as diversified long-term holdings.   

Have you ever done any daytrading (traditional stocks)?  Daytrading cryptocoins is not like daytrading stocks, the markets behave quite a bit differently.  It's also nothing like poker.

I have been successfully trading cryptocoins for a quite a while now and I would recommend the following steps:

1.   Attend some conferences or watch some conference recordings.  It's important that you understand the underlying concepts, terminology, etc. to cryptocoins, and the industry they operate in.  Personally, I feel attending conferences in person is far superior to watching anything on youtube.    

2.   Keep on top of cryptocoin news.  Twitter is essential, so is this forum.  

3.   Invest a significant amount of your time to watching how the markets behave, correlations to certain market behaviors, understanding the industry as a whole, etc.  

4.   Start small - it's easy to grow even a small amount of capital when you've successfully learned how to trade crypto coins.  You can always invest more when you've demonstrated to yourself that you can perform successfully.
