Well, we already have another thread praising bitcoin or bitcointalk, which if I were wrongheaded I would say is an attempt at merit fishing.
1. You must split your coins in 2-3 wallets, to avoid losing all your coins if they are all in one wallet. But then you don't know what types of wallets to use.
Take note that this isn't necessarily the best strategy. While you avoid losing all your coins in one go, it increases the chances of you losing your funds partially.
What do you think it is worse? It's clear to me.
On the other hand, I only see sense in it if you have enough liquidity. If you have 0.05 Bitcoin I think it's bullshit, and even more if you are going to have it in HW, which is how you should, because you are going to spend 20-30% of your holdings in custody.
Then you would have to take into account other things, for example, you will have physically remote places to hide them, right? I wouldn't see the point of having your holdings distributed in 3 wallets but hidden in the same house, even in 3 different places, because you would have a high risk of being robbed with a 5 wrench attack.
