My choice to hold 0% BTC was profit based. That was it. I also spread my ladder wide so some rungs are in the $6k region and that to me is best to cover further upside. The rungs that don't get triggered will be my left over BTC balance.
My % USD is now pretty high. That's intentional to hold dry powder for the Wave IV bottom. I don't necessarily see having >30% in cash as being risky but safe.
It's better to be out of the market and wishing you were in it than being in the market and wishing you were out of it.
Nicely put. However, I believe we must stay open-minded as there will be a time when you will be 'in the market' when you are in fiat.
