4. I even store my coins on wallets like Free wallet which is a very bad one, never knew about centralised and decentralized wallets, I ended losing 1 million doge coin to Free wallet
This has been the mistakes new people that just know about cryptocurrencies do make, my first wallet was coinbase.com, I did not even know there is anything called seed phrase or private key. My second wallet was Coinomi, I did not even know there is anything called close source and open source wallet. I started to know about bitcoin and other cryptocurrencies in November 2019. But can you tell us further how you lose such huge amount of doge on Freewallet? Although, if it is not your key, it is not your coin, using noncustododial wallet like Electrum and hardware will be perfect.
Just know that you are not late to know all these.
