Yes, anyone that wants to be a trader in cryptocurrency must learn the analysis.
If you are only going to play the long term hodl you wont need much of an analysis for bitcoin. Because we all know that bitcoin will rise in future since the deflationary condition of the currency makes it scare as the population demand keeps on growing.

Some will say the market is unstable and they are afraid that they will lose money when they invest in it, but there are people who are able to get in and out of the market few hours a day and they are also making it despite the volatility. I heard a story of someone who didnt even learn it and all he was doing at first was buy when it seems its going up and sell when it seems to go down and it worked quite alright for him till he got to be perfect.
Those are just stories mate. Rumors made to insinuate you to join some whale pool. Dont worry they are just going to make you pump their shitcoin when they will sell it. Also dont fall for loan sharks giving out info for margin trading.Actually those who manage to make profit from short term flux are those who were holding the coins for sometime and they sold at the pump. The rest who come running after that are now in loss because its a shitcoin now and wont go up immediately.
