That would make Bitcoin a very good store of value. However, to benefit from the "store of value" property you have to, you know, actually store the bitcoin yourself, not sell it now and try to buy it back later…
If I borrow a Bitcoin what makes you think that I can repay the Bitcoin after it grew 10x in value? Who is doing 10x the work? (10x more productive)
