To achieve $1 Million by investing Bitcoin, you need around at least $200K since if Bitcoin made new ATH at $100K, it mean the price already 5x times more higher from your beginning capital.

If you want to achieve $1 Million by just using $10K, then you need to be patient since you need to wait the Bitcoin price x100 times more higher than the current price e.g. $2 Million.

Don't think to made instant profit, you can just do DCA-ing to buy every dip of Bitcoin until you reach $1 Million.
