Don't get me wrong but you don't need to keep anything like in percentage.
What is your aim : HAving 1m from 50k in 365 days.
With buy and hold it is possible but it has a very low possiblity than buy-sell.
If you buy and hold 50k crypto with a percentage you need an increase of 2000% in a year.
But if you want to catch buy-sell with increase of 20% for 17 times that means 1.1M USD around.
I think possiblity of catching 20% increase in a week is very high than catching 2000% possiblity with buying and holding a compost of cryptos..
