I think many other big amounts were now stored in bech32 or segwit addresses safely, don't know why some claim segwit is not safe. Although Bitcoin cash supporters will never stop claiming segwit unsafe.
The basic idea is that miners could collide to maliciously steal funds sitting on segwit transactions as they would be revertible due the "anyonecanspend" thing which a lot have talked about since segwit started gaining traction back in 2016.
So far, not a single satoshi has been stolen from a segwit address. As addresses hold more and more money and time goes on without a single satoshi stolen, it will be proven that the supposed attack was never viable (otherwise why wouldn't miners do it).
If this is true, then we are certainly stepping in to a new and positive era for bitcoin. We should immediately move to segwit enabled wallets and start using segwit addresses start with 3. It may solve the network issue for us and create bitcoin a better currency for all of us.
It shows how Bitcoin is the ultimate tool to move unlimited amounts of wealth for very, very cheap (other coins aren't decentralized and aren't robust enough, neither have the liquidity).
But a transaction fee is derived from its size, that is the amount of inputs and outputs so the amount that you are trying to move is irrelevant afaik. When you are trying to make a transaction using a lot of different addresses is when it gets more expensive. This is a problem for people that receive small amounts of bitcoin payments. For example if you recieve bitcoin payments for a signature campaign across a year in the usual weekly payment schedule, you would average 52 received bitcoin transactions per year from a signature campaign alone, not even considering other payments from other places.
So if you wanted to move the sum of the 52 payments in a single address, even if the total is only 1 BTC, it would be more expensive than moving 40,000 BTC that are sitting on a single address. This is a problem. Im not sure how cheaper it would get by using segwit, but I reckon it will be still pretty expensive. Probably until schnorr signatures or some other things come along, it will remain a problem.
