Do we really think anything bad is going to happen to Coinbase?
If it does then the whole market will go down and there will be limited bull run.
I sent more to my cold wallet yesterday anyway , i now have 30% on Coinbase and 70% on my cold wallet.
I just like having some on exchange as it is easier to take profits quickly once something has pumped.
Nobody thought anything bad would happen to MtGox but it happened and the market went down like there was no tomorrow. About limited bull run, I don't know, covid made BTC fell to 4k before last halving and it went up as expected, but there is no guarantee on what would happen now.
JamesDaniel90, you're free to do what you want with your investment. Cryptos are risky for several reasons and we might, for example, feel safer hodling for the long term in our shiny hard wallets and wait for too long before liquidating, after an eventual crack or disinterest comes and makes our investment worth much less. And, in that case, you'd have made the right decision holding a part in a CEX and selling at the right moment.
Chances of happening the contrary seem more probable, at least in this forum, but who knows. You already know the version of the majority, so you can make an informed decision.
And, about the fees, you're already aware too that liquidating that way will mean some costs. Assume them or calculate alternatives like swapping your coins to the one(s) with the cheapest transaction costs before withdrawing. And if the costs are not too high and doing your own research on how to reduce them will make you lose time that is more valuable to you than the potential savings, don't give them too much thought.
