According to the topic at that period a lot of people want to sell their bitcoin or altcoins so fake vendors will come up to deceive sellers so at that time I will also advise people to sell their coins in the platform ls that are more popular and not the new ones. Please avoid individual and new exchanges in the bull market.
Simply use a Local exchange to easily make sales or a Tier 1 Exchange like Binance so you don't get confused to start selling.
Here the concern is not where you sell although in some Exchange bars, what is more dangerous is the Phishing Link disguised as the top Exchange.
There are a lot of emails I get from scammers to get into the top Exchanges, even though they are phishing links.
As well as some links embedded on social media or from unknown people.
Because during this bull market, many scamming methods are done to trap early users or old crypto users, so you have to be more vigilant.
