Why btc still slow and expensive ?

[JiiBs]

Why still haven't improved? Btc still slow and expensive to send transactions and for sure time like tron has you know that transaction allmost instant wich not the case with btc
Whos fixing that and what could be improved ? And when btc to POS so we don't depend of miners i don't think i want to or trust put my hard earned wealth in mercy of miners,well that's just me i like everything to be perfect and secure but ye btc slow still tron is way better

There was a time when Bitcoin was sent at an instant, the same goes for some of the altcoins out there like ETH and a couple of them. Even the fees in these times were relatively low, perhaps low in value as they didn’t worth much at the time but, most of us were yet to take up cryptocurrency investments so, we just didn’t get to experience it.

What does that mean?
It simply means, the more the currency and its Blockchain continues to offer solutions, exists longer and have projects built on them, the more it’s got a lot to do and the network is burdened with tasks. This has lead to several chains being developed such as the Tron project you now mention. It doesn’t mean it wouldn’t get slow or the fees wouldn’t see significant increase.

Yeah, Bitcoin's speed and fees are a total bummer, right?  It's like waiting in line at the DMV, but with way higher stakes!  Tron's speed is definitely tempting, but remember, speed isn't everything.  Think of it like a sports car versus a tank , one's flashy, the other's built to last and withstand a nuclear apocalypse, hopefully
Bitcoin's slowness comes from its security model and it's designed to be super secure, which means more verification steps.  Improving that speed without compromising security is a HUGE challenge.  So for me The whole miners thing is a valid concern. It's a bit like trusting your bank, but with a distributed system of heavily motivated people , so that is all I have to say

Any cryptocurrency has parameters such as security, decentralization and transaction speed.

In practice, only two of these parameters can be improved. Improving all three at the same time is impossible. No one can create a perfect cryptocurrency. It is impossible.

The value of Bitcoin is in its decentralization and security. Transaction speed is not that important. Bitcoin allows you to transfer large amounts of money over long distances. Bitcoin allows you to own and manage funds without the mediation of other people. Bitcoin allows you to conduct transactions without censorship....

Isn't that enough?

With Bitcoin, you will never face a situation where your funds are blocked by financial intermediaries. And in the modern financial system, such situations happen all the time.

The PoW process is especially used in cryptocurrencies like Bitcoin. This process keeps the blockchain secure. In the PoW process, the decision-making power of the blockchain is divided among many miners, so it is not under the control of a single party. It is a completely decentralized system. No one can control it alone. But PoS can maintain the advantages of fast transactions and energy efficiency. However, this method can sometimes create the risk of centralization because in this method, large stake holders get more control over the network.

It's called the blockchain trilemma. It's the reason why we haven't gotten any blockchain yet that has the perfect blend of decentralization, scalability and security. If there's one thing I've learnt in my time here on the forum and in crypto overall, it's the fact that something has to give.

You either get super fast chains like solana and sui and risk using a centralized chain.

For instance, most layer2s are powered by multi-sigs.
