Of course, large exchanges have more liquidity and seem more secure. But it is not always the case. We know that volumes of trades are bloated on almost all exchanges. This is often done not by exchanges themselves, but by projects using trading bots.
Plus, such exchanges as Cloinsbit that they feature many young crypto projects that do not have the opportunity to get on top exchanges like Binance and Huobi.
Many traders use trading bots ... many teams of various projects use their own trading bots ... why are all statements about bloated volumes directed only to exchanges? exchanges may have nothing to do with this.
There is a little difference between trading bot and exchange bot. I myself led to the fact that I set a buy and sell offer between which there was not even 1 satoshi difference. For example:
Sell: 0.00003001
Buy: 0.00003000
At this point, the trading bot stops. The smart exchange bot should also stop. This exchange bot did buy and sell transactions at the prices I set and there were no other offers because there were only these two mine. Of course, nothing was bought or sold, but transactions have appeared in history, so it could not be a bot from the outside.
