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.
After the FTX case and all the chaos of centralized exchanges then I think anyone should consider these tips as well:
Reminder: do not keep your money in online accountsIdeally, you should keep as large a percentage as possible of your crypto assets in a wallet where only you control the private keys. Electrum for Android or desktops is one good option. For iOS, there's BlueWallet. If you have a large variety of different crypto assets that you need to store, there's Unstoppable wallet. If you have never used your own trustless wallet before, using a mobile app is probably safer than using a desktop app. An even safer option, which you should definitely consider if you have a lot of crypto assets, is to use a hardware wallet such as Trezor or Ledger.
Unless you can choose a few recommended wallet, then you should consider not keeping your assets on the exchange for an amount you cannot afford to lose. Of course for certain amount you can keep it on the exchange, but for long term investment then you need to consider wallet that you have complete control over. Have self-custody for your assets, it's much safer for your goals in the long term.
I think it is time to end the drama about the issue concerning FTX. For sure many of us are aware of the risk of putting your assets on exchangers but still, people still continue such habbit. But I won't force them not to do so 'coz they might be trusting their exchanger that much. If we would look back to past, scams were on projects and rarely with exchangers. To my awareness, it is only FTX which became careless of their funds which yield to irreponsibility and collapse but that does not conclude that every exchanger would also do so. Indeed there is the slightest tendency, but generalizing will just result to FUD and bigger problems.
Going back with the topic, indeed this technology would make you aware of things, mentally. From planning, controlling oneself with actions, to speculating. But I doubt that is only due to this technology. It is applicable to lmost everything, it is just more emphasized on this blockchain because volatility is too high.
