Bitcoin is actually the end game of my investment, I won't convert it to real estate, land or business.

Renting real estate or land? I can earn more just by investing in Bitcoin.
Business? I don't have time to manage it.

Not to mention I would face unnecessary dramas e.g. they claimed to own my land, I could be scammed, the lessee don't want to pay the rent, cost to maintenance the real estate etc.

I only sell my coins to accumulate more coins.
