When u hear/read a coin have a burning plan in their roadmap - is it a always buy in before and sell when it happen? ( Excluded shitcoins).
Depends on you but always mind of about the risk because not every burning events would typically means guaranteed pump of a certain coin even its a top ranking one
but still wont give out some assurance.
Therefore, it would really be varying on your own risk management if you could really able to afford it out on investing into that particular project.
Its your money then its your decision to make not on other people.
