I think that I will not say anything new if I offer a regular cold wallet. Or two? Or three? I also think that bitcoins should not be stored in one place or one wallet because there is a banal human factor and should not be underestimated. Suffice it to recall a guy who is still looking for his old laptop beech in landfills, on which, at today's prices, there are about 220 million pounds worth of bitcoins. In order not to go crazy from such upheavals in life, it is worth thinking about safety in advance.
