Hello, maybe this is wrong topic, excuse me for this.
I have a problem, that I bought previiously xrp and polkadot on crypto.com app, amd sent it to my Atomic Wallet. When I wanted to sell my coins back to crypto.com and from crypto.com to my bank account, I was attentioned that 1 DOT and 20 XRP must leave in my walllet. I said what? This is my 20% of my coins. Large losses, it is a disaster. Hen the support said that something it is with dot and xrp contract, so not thhe wallet miistake. It is what it is, for everybody,or justme, or can I do something? All coins what I have must leave in wallet some enermous percentage, so clear losses? Wtf, what can I do now?
When you buy, sell, and withdraw your crypto, you have to know the transaction fee (on the network) and the withdrawal fee in the wallet or on exchange you are using it to make that withdrawal transaction.
Withdrawal fees are often very high on exchanges and the smaller the amount you plan to send out, the more carefully you need to check details. Sometimes, with some coins, withdrawal fees or transaction fees will eat almost the all value of your transaction.
Those details are given at the time you are filling your withdrawal request, so please check it and find more in their page (ToS, FAQ).
some exchanges do charge higher withdrawal fees. and it all depends on the policies of each platform. when we forget to take all of that into account, what we sell may not give us anything. Currently, almost all token and coin transactions have increased transaction fees. as seen in the price of tokens or coins that have increased, but it turns out that you also have to prepare a larger fee to be able to sell them and make withdrawals.
