With crypto you can get huge returns. However, it doesn't come easy, in a split second you could get or loose a large amount of money. This means crypto trading is exciting, and it can be very difficult to keep peace in mind under heavy pressure.
The easiest way of making money in crypto is investing longterm. Rather than trading you can buy coins, hold them in your wallets untill the price appreciates and you sell and make your profit. Of course you have to make some research about the coin, and be convinced it has potentials before investing in them.
Another way you can invest is day trading, which is a trading strategy where investors buy and sell orders for multiple times in one day. This requires more knowledge and skills. I suggest you use a demo account.
With your advises I think you are in crypto scene for long.
It is not a trusted advise if you only join crypto scene in one week or one month. In short period, you can get huge profit or huge loss but you won't never experience all emotional challenge in crypto market.
You should store your bitcoin in your wallet, not store them on exchanges but the wallet you use must be a non-custodial wallet. In addition, you have to secure your wallet private key or mnemonic seed as much safely as possible. The same goes for backups.
