The veteran people on crypto tend to say that you should keep your coins in your wallet, never on exchages. However if there is a strong downwards movement on a coin and you want to sell to buy latter at a cheaper price it may take quite a bit of time and fees to move it. What is the right strategy?
There is no doubt that time is of essence when there is need to make some decisions concerning the holding of stocks just like bitcoin increase in price from $8000+ to $8100 within the hour but that does not justify keeping all your funds in exchange sites. What is being suggested is that keep only the amount you will need on exchange sites in case if anything should happen, you have something to fall back on. And today there is less traffic on the network meaning the time lost can still be minimal in transferring from the wallet to exchange sites.
I agree with you olubams about keeping an amount to be used on exchanges but determining how much should be kept there will also be an issue for the trader. As a day trader you will always need ready cash in bitcoin on the site of your choice for easy trade in readiness for any pump alerts. When you talk of keeping small, what percentage to be kept are we talking about here?
