Not your keys not your coin remains the best.

But let me add some that I usually tell newbies.

- Before you start accumulating Bitcoin, ensure you have an emergency fund. This is because you might be forced to sell because of unforeseen problems.

- Don't give in to FUD. You can achieve that by getting information from reliable sources like Bitcointalk

- Safe wallets: if you can afford it use a good hardware walletswallet to store your coins.
