I'm not sure what you mean by this. In a "normal" system, you don't trust third parties to create transactions to begin with. Third parties use a centralized system to create the transactions and you trust that centralized system.
The fundamental premise of cryptocurrencies is decentralization, although in practice it turns out to not really work that well. Most uses of blockchains end up not actually being decentralized, or not gaining any benefit from being decentralized (and definitely being less efficient than a centralized system). And you end up with situations like the DAO hack where this supposedly-decentralized system still ended up with a centralized governing body deciding to roll it back (and yeah, it was forked because some people disagreed with this, and it's kinda neat that that was even possible, but Etherium Classic currently has a market cap worth 3% of Etherium so it doesn't seem to have been very effective).
> Uncensorable donations to wikileaks
This is one of the few actual genuine use-cases for cryptocurrencies, though even here it doesn't actually work that well because most cryptocurrencies that claimed to be untraceable are in fact traceable. If you don't care about tracing, well ok, but unless you're living in an all-cryptocurrency world (which pretty much nobody is) you still have to convert to/from fiat, and that conversion point is where governments can apply pressure if they decide to act.
Though maybe one of the rare cryptocurrencies that seem to actually have genuine untraceable transactions might become popular, who knows?
> Avoid having PayPal or other payment processors freeze your merchant account for X months, on a whim
This didn't go away, just replace PayPal with "cryptocurrency exchanges". Maybe they're not freezing your merchant account but they're causing other problems.
> Avoid the risk of charge back fraud for online payments
At the cost of being unable to initiate a chargeback if you're the buyer and got defrauded. The chargeback mechanism exists for a reason.
> Financial privacy for everyone not just the ultra rich (lookup Monero before commenting)
This really only applies if you're actively trying to lie to the government (i.e. if you're doing illegal transactions and don't want them to know). Using cryptocurrency doesn't absolve you of the need to pay taxes, so for most people the idea of "financial privacy" doesn't really matter because they have to tell the government anyway.

Third parties use a centralized system to create the transactions and you trust that centralized system. For example as a merchant you don't have to trust PayPal with your money and trust them to process credit cards from the buyer and then send it to you. You can just accept payments digitally directly like if they gave you cash in person. > This really only applies if you're actively trying to lie to the government I value my privacy and I don't want my transaction history to be sold to advertisement companies and the like.

- lawn 8y agoGiving a single entity like your bank, credit card provider or PayPal your whole transaction history is quite different from giving many merchants a small part each. It also allows you to pay digitally in person and avoid transaction records in some cases.

You're just moving your trust around. You have to trust that the cryptocurrency system was implemented correctly and without bugs, and you have to trust your wallet to be implemented correctly and without bugs, and if it's a hosted wallet you have to trust the hosting service, and if it's a local wallet you have to trust your local system to ensure you don't lose your key or get hacked. Also since we're dealing with a different currency now you have to trust that the currency will actually act as a stable store of value. Or if you use something like Coinbase to accept bitcoin but immediately turn that back into USD, you're now trusting Coinbase to process these transactions.
