Not that I disagree with that ratio but I'm not doing that.
I hear more people use 5%-10% on alts. (initial value)
As the price rises they often cash out to keep that % (or maintain a certain percentage.)
That said I do feel like Monero is worthy of taking a bigger risk on as I have more than a strong feeling that many early
BTC adopters see what is happening and they want to up the ante with XMR.
IF XMR is showing this kind of strength with BTC relatively down, I can only imagine where it goes once BTC turns upwards.
My guess is from .01 BTC or .02 BTC on the lower end, to .1 BTC on the extreme high end.
So, being that we are in the .003-.004 range, a higher % of BTC in XMR is a decent chance to take.
What timeframe are you looking at?
The .01 ratio can happen overnight but I imagine in the next 3 months or so we see it happen.
My extreme high end ratio would involve unforseen forces as I can't see under normal circumstances that happening. But then again, when the public moves into Crypto en masse, all bets are off
