Wow...that's a huge discretionary income for plebs like us and like you said, we all have our different ways in which we would use that $10000 to invest into bitcoin.
Personally, I will divide the money into three parts since I already have an emergency funds available. I will use $3000 to frontload my bitcoin investment, use $2000 to keep for buying at the dip and I will use the $5000 left to spread across several weeks for DCA buying.
That's clearly a significant amount of discretionary income.I think if someone has $10,000 in discretionary income and wants to use it to buy Bitcoin outright, regardless of the price, or better yet,
buy it when the price drops, neither is a bad idea.The important thing is to do it for the long term and not stop there. We can continue making periodic purchases or use the DCA method using existing income and continue using discretionary income to buy Bitcoin and also for an emergency fund to add to an already large holding and make it even bigger over the long term.
Sir jayjuangee has said this countless times here that waiting for a dip in price of Bitcoin before buying is a wrong approach because by waiting for the price to dip, you may miss a whole lot of buying opportunities, so you saying that someone that have such an amount that wants to acquire Bitcoin should wait for it to drop is not ideal because you are saying indirectly that the person should wait before buying, and that's a terrible advice if you are giving it to a beginner.
