All about patience. He may not be a fan of crypto but this advice is still the best.

"The Stock Market (replace with "Crypto Market"!) is a device for transferring money from the impatient to the patient" - Warren Buffett

Additionally looking at market news, reading reviews, trading signals and getting an overall feel for the opinion in the market can be a highly helpful.

Plus have in mind your exit price and stick to it, trade out your positions, take a percentage profit out regularly into fiat (e.g. at the end of the month or weekly).

Trade with logic not emotion and be prepared for the value of your portfolio to dip. If you can ride the dips with nerves of steel, you're half way there!
