I advise you to calculate your strategy based primarily on your own skills. It is not so important what size your deposit is, in any case, you must divide it into several parts in percentage terms.
Only then decide which asset and how many percent you are willing to trade. It will be much easier for you, because in fact your deposit itself will be divided into several parts.
