What if my Bitcoin investment was reduced to zero, I don’t resell, later it gains the momentum after a year or two, will I still be owning it to claim the returns?
The amount of bitcoins you own will always remain the same, regardless of their price. So if you have 1 Bitcoin today when price is $18000 or so, then if price goes to $1 tomorrow you will still have 1 Bitcoin.
It’s the same as owning any asset, like gold coins. Their price changes but the amount of coins you own is not affected.
