BlackRock sold over $190 million worth of Bitcoin

On-chain data shows that BlackRock has sold over $190 million worth of Bitcoin. If true, it indicates, as I worried and imagined, that Ethereum has all the attributes of Bitcoin but can do many things Bitcoin cannot. So why not hand over everything that official and large financial institutions want to do to ETH, making Bitcoin feel like a spare rib? New technology company grassroots applications and innovations can all go to SOL. The world would be perfect and simple.

I can't convince myself of Bitcoin's unique property as digital gold. Because it shouldn't be hard to stop ETH issuance. And let's not forget why gold was abolished in the first place. Because of this concern, I no longer hold Bitcoin.

I sent my above text to GPT5, and here is GPT5's feedback

Bitcoin ($BTC): Its main value proposition right now is 'digital gold'. It is the most decentralized, secure, and simply designed. Simplicity is both an advantage (not prone to issues, trustworthy) and a disadvantage (single-function, poor scalability). If the world eventually believes there is no longer a need for a purely 'store of value' asset but rather prefers programmable currency, then Bitcoin's status may be weakened. On the other hand, many institutions and individuals still want a neutral, censorship-resistant, and uncomplicated reserve asset – so the narrative of 'digital gold' remains sticky.

Ethereum ($ETH): As you said, ETH inherits some characteristics from BTC (scarcity, decentralization, security), but also adds programmability (smart contracts, DeFi, asset tokenization). It has already become the main platform for government bond tokenization, real asset on-chain, and institutional pilots. If the global financial system eventually needs an 'official' blockchain, Ethereum is the strongest candidate because it has found a balance between decentralization and functionality.

Solana ($SOL): Due to its fast speed and low fees, it has attracted consumer applications, grassroots developers, games, and social protocols. It is more like a 'startup chain' – where experimentation, high throughput, and user experience are more important than extremely conservative governance. If Ethereum is the settlement layer, Solana could become a paradise for daily innovation and applications.

So, your idea (BTC = possibly gradually marginalized, ETH = financial and institutional foundation, SOL = consumer innovation layer) is indeed concise and attractive.

The critical question is: does the market really need all three to coexist in the long term? Bitcoin has the first-mover advantage and ideological support; Ethereum is gradually becoming the infrastructure for serious finance; Solana aims to capture the Web3 application layer. In the future, it may converge, or as you said, each may specialize and form a complement.

👉 My (GPT5's) view is: Bitcoin may not become 'useless', but it may solidify into a niche 'reserve asset' with limited growth potential; while ETH + SOL (and even other chains) will carry most of the innovation and practical value.
