There is no secret or right way to trading.
It all comes down to experince pretty much. I have been trading stocks, futures, forex, bitcoin for almost 10 years.
Basically the best way is to look at the longer term charts and try and time trades off the short terms charts.
Basically in my opinion. Bitcoin is a long term bull, short term bear, and midterm a little bullish.
You can use TA to help you but keep in mind it maybe only works 20% of the time. The rest are fundamentals.
I would agree with the conclusion about bitcoin trading,
But I think when trading cyrpo my best profitable method is to set a goal for short term, and keep up accumulating in one coin you're believing in and trusting as main feature of the crypto is trust ,
My current strategy : buy price + sell price 10% only , and then wait till the coin falls in a big dip then buy again and sell in 10% increment, playing it safe might be the best way in crypto as people don't know how volatile crypto can be when they start and it scares the shit out of anybody that done trading, so it's not as easy as it seems.
