I'm wondering just what the hell is it: when you trade on Binance, you cannot trade your full amount of coin and some amount is kept for every coin you trade.
Is there possibly a way to get rid of it?
I searched the web and they proposed a solution: to trade the coin with BNB, but even with this solution the problem still exists.

I have some money not more than two months later. In which coin should I invest? I searched to find my answer, but advices are for long-term investment.

you can check the true wall size for this coin here through their API:

this is just another bug on their website.

Here is their explanation:

No pre-pumping: you can look at the charts after the announcements for checking whether they have been pre-pumped or not.

No sharing the coin name privately before the announcement: you can try me by messaging me and asking to reveal the coin name by offering money and I will reject it. All members get the coin name at the same time.
