Let's talk about private keys and addresses.
Bitcoin and Ethereum private keys are both actually 256-bit random numbers, and both use the secp256k1 elliptic curve.
One easily overlooked point: an address can be thought of as an account for receiving funds, while a private key is the sole credential for accessing those funds. You can share your account details with anyone, but only you should keep your private key safe.
To receive coins, you only need to provide your address. You never need to hand over your private key or recovery phrase under any circumstances.
The coin mentioned above: $BTC , current price 76054.01 (24h -0.28%).

There’s quite a bit of volatility, so manage your position size carefully.
