Hmm, 10x is actually pretty small IF it was the past. These days I'd assume that Bitcoin growth is going to decrease exponentially compared to the past, so the 1000x you'd see in the past would go down to 100x, 10x down to 2x and lower even. It is for a couple of years but I don't think it'd be feasible at all with the market (unless we see a 10x the next year, which I highly doubt) so you might need to short every now and then and try to maximize the small pumps/dumps of the market.

As for investing Bitcoin itself, no I don't think a 10x is possible at all. It's already a risk in itself so I don't think you need to go beyond that, not to mention I don't think it can even be used to invest on a market stock/asset.
