Hi @louisthomas,
People make fresh investments into bitcoin at two points in recent years. 1. When BTC create hype and gone to 21K$. 2. When BTC fall from sky and get 3200 - 3500$ position. There are nearly 0.8 Million new Bitcoin addresses that hold balance at-least 1 BTC.
When we talk about ethereum, It's about Dapps (Decentralized Apps) and his amazing feature smart contracts enabling many people to create applications and games with custom tokens also, on ethereum blockchain.
Thank You.
