Does it make sense to create a hot crypto wallet?
If you are going to buy and sell cryptocurrency right there, then yes, it makes sense. These ongoing transactions over the Internet will require you to own such a wallet. Otherwise, I see no point in creating such a wallet. For experienced businessmen who deal with large sums, I would like to advise you to start a hardware crypto wallet https://entheca.com/ - a friend started it with me, he recently boasted. I am very impressed, it feels like a personal assistant in your pocket who knows about all your affairs.
I am currently using electrum wallet for holding BTC that I earn from trading through my crypto bot (here you can check this paltform https://tradingbot-solutions.com/). But my advice is to not leave your BTC on any exchange for too long.
