Am just holding - don't have a lot so no point converting it to Cash and then it will be wasted on some useless expense. I have always considered Bitcoin to be a store of value, like gold, which I prefer to just keep and never sell.

Yes, the value of bitcoin will rise, perhaps up to eternity, however I won't be alive to see it - but the same thing is true for all assets that we keep for later - like house, land, gold even shares of companies that are ever green. Hopefully someday, someone from the family will take it up further and keep growing it as long as they exist.
