A video which runs through an example of the ways that traditional hardware wallets fail to provide the security needed for DeFi when blind signing. (An issue for NFTs, farming, swaps, etc) Demonstrate what this looks like with Pancakeswap, Sushiswap and Crypto.com Defi Swap, using a Ledger, Trezor and Keystone. Demonstrates how to perform Smart Contract verification in Metamask, on a Keystone and also on a Ledger Nano. (for Paraswap) This is an issue on any EVM chain, so Ethereum, Binance Smart Chain (BSC), Avalanche, etc.

---------------------
If you are new to Crypto, my suggestion is that you start with buying ~$150 worth of Bitcoin, Ethereum, Litecoin @ Coinbase and get familiar with storing it, moving it around, etc.
For your first purcahse, just stick with CoinBase: www.coinbase.com/join/5691c9d...
For Trading, just start with Binance: www.binance.com/?ref=18111926
By sticking with large, reputable exchanges for your first purchase (Coinbase) and first trade (Binance) you can avoid getting scammed right at the start by purchasing a non-existing coin off a scammy exchange. (You would be surprised how many people fall into this trap)
Don't have a hardware wallet?
Be safe and buy them direct from the manufacturer. (Not just through some random on eBay, Amazon, etc)
Get a Ledger: shop.ledger.com/?r=5243ecbb84...
(If you are just starting out, I would just recommend a Ledger Nano S)
