Advice for beginners and non-beginners who still make mistakes
DO NOT buy coins that have already entered a bullish cycle, unless you have enough psychology to withstand the corrections that will happen!
Study a project, research and accumulate that coin(s) in every correction it makes and hold it for the long term. If you buy after it has already gone up, you will hardly make enough profit to be happy and want to continue investing. So, always take advantage of corrections to BUY and if necessary, take advantage of the rise to SELL! But remember, this advice is for those who hold for the long term.
If you want advice and strategies for short-term profit, follow other people's advice, because I do not operate as a day trader!
