I have a problem with people even having to use part of their Bitcoin holdings to trade. I believe in separation of concerns and precision which spurs effectiveness.
Why will you even be trading with your bitcoin holding? It doesn’t make send to me, if you are planning to hold your bitcoin, then it’s better you hold, but if you want to trade, then just focus on that, and if you are planning to do the two, just split the money you are having, leave some in your investment wallet, and be trading with one part on exchange, but touching your investment money frequently doesn’t really go well.
I think if you must trade, trading wallets should be handled separately and holding wallets should be treated separately.
Traders do make use of exchange to trade, so most of them do leave their coin on exchange pending when they won’t be trading for some time, before they withdraw it, but if you are planning to hold, then your money shouldn’t be on exchange, you should be in control of your money always, don’t leave you money in exchange, because if anything happens to the exchange, you might end up losing your money, and we should know that no exchange is too big to be compromised.
To me I don't see trading and at same time inventing as a good idea because one day you might be tempted to touch your investment or discretionary to trade because of loss incur in your trading. However, trading has a very big spirit that is like gambling addiction and whenever you turn an addict, you can even go as far as selling your Bitcoin investment and when that one is gone you may still go and Borrow to trade that is how dangerous trading can be apart from the fact that it is very risky, so whosoever that wants to trade should just go straight and whosoever that wants to invest should also go straight instead of mixing or doing the two simultaneously it doesn't make sense, it is not a good strategy or approach.
