Address types

[dkbit98]

There must be an agreement in consensus* to remove the Legacy address type, just like when a new address type will be implemented (for example, P2TR type).

There is no chance for this will ever happen with any consensus.
Removing old addresses would mean hard fork and totally new supply of coins, and many old coins would be gone forever, including Satoshi's
Imagine someone who holds coins for years in cold sdtorage and then bunch of experts decides to make them worthless and unusable

Have you tried exch.cx?
No kyc, and they accept bitcoin lightning payments.

I haven't tried it, I know it's through BTT, as exch are Automatic cryptocurrency swaps but that's not what I want. Then their fees are not cheap, around 5%.

In any case, this is not a problem, and so as not to go off topic, my question was why exchanges are not forced to upgrade? and it seems that the closest answer is that they do not have to pay additional costs for the upgrade, as users are the ones who pay the fees, so they will most likely not change anything.

I also believe that soon all exchanges will switch to KYC so the wallet remains the best solution even if there is an increase in fees.

I also indirectly deny that it will happen. Even if a proposal proposes this, it will most likely also be rejected. Besides the fact that many old Bitcoins are still stored in the Legacy address type (P2PKH), this type is still safe to use, unlike P2PK, which has several risks, so Satoshi replaced it.

Regarding yhiaali3's question below

my question was why exchanges are not forced to upgrade?

The only thing that still allows users is to look for exchanges that have many options for Bitcoin address types other than legacy types.

I don't know who told you that, but this is not the same fee you need to pay for all coins available on eXch exchange, it is only for Monero pairs.
For example exchanging Bitcoin to Litecoin fee is from 0.5% to 1%, it is the same for Lightning Network, USDT, and all other available coins.
No other fees, no registration, and it all works fast.

Thanks for the clarification. Yes, this is a misunderstanding on my part. I only tried exchanging between Bitcoin and Monero, so I got a 5% fee. I did not try the other pairs, so thanks for pointing out this point.

I wanted to transfer using USDT on the Tron network, but I did not find it among the options. I only found USDT on the Ethereum network, so I tried Monero.

They are very cheap. Their fees are 0.5%.
No withdrawal fees. For small values, it is much cheaper than usual CEX, and as I said, no KYC and no smartcontract fees.

You will pay about 80 USD in mining fees for the same service using uniswap.

I think they are working on adding more option for USDT and other stable coins, Tron support could be added in future, and probably L-USDT on Liquid Network.
My suggestion for you is to try Aqua wallet for mobile devices with support for BTC, Liquid L-BTC and L-USDT.
Transactions are much cheaper and there is an option to receive/send transactions from and to Tron and Ethereum with 1% additional fee, and it converts it to liquid.

The lightning implementation is very good. I used it a few times and it worked very well.

Thank you, Aqua Wallet This seems to be what I'm looking for, a non-custodial and open source wallet, it seems like a perfect fit for me.

Since it supports BTC, Liquid L-BTC and L-USDT I expect I can convert BTC to USDT easily without the need for a centralized exchange.

I will try downloading the application and depositing some Bitcoin, then I will explore the available options. I hope it will do the trick.
