If i was holding kilos of gold or silver, i would not dump them only to buy cryptos, and if someone does that, then he is a dumb, i know that we all are strong believers on bitcoin, but it doesnt mean that bitcoin is the most safest thing since year 1. You all know that someday it could just drop, or something like that.
Gold has been the most safe currency for more than thousand of years, i dont like to see it replaced by bitcoin, it is something weird, and there is no way to check it.
Actually, I will not do the same but the chance right now, crypto have much potential to get the profit back compare to the silver, although you loss some on silver, in crypto you will get that instantly. So I think if they dump it and start to buy crypto right now then it is really a good choice. But if they want to have a very long term investment may be they should not dump it and try to buy everything they can including aome crypto
