[CONTENT-CHANGE] Remove "Use Cryptocurrency for Online Transactions" about personal-security-checklist

[Lissy93]

You are right in a lot of this, and I agree, that in order to do this properly and securley, the learning curve is very steep.

It's a real shame that there are so many crypto scams, pump and dumps and shit coins out there at the moment, because many cryptos are based on some awesome technology, and have great potential.

I personally use XMR (and sometimes BTC) to transfer funds to friends abroads, and find it really useful for avoiding high international transfer fees,

I think this comes down to skill level, threat model, personal preference. I will update this part of the list, and maybe link to this issue, as you've made some really good points.

If you’re buying BitCoin at an exchange, then I agree that this would be pretty terrible for privacy. But if you primarily use something like XMR, or you are savy in how you manage your wallets (exchanging cash for crypto, not reusing wallets, self-custody etc), then crypto can provide the ability to send funds to anyone, anywhere that just isn’t possible with cash, and can’t be done privately with transfers / payment processors.

That's kind of what I meant by this point anyway, do you think I should re-word it to highlight those risks (public ledgers, exchanges etc)?

I would definitely at least mention tradeoffs here.

For start significant research is needed, there are new unexpected failure modes, typical uses are not privacy-preserving at all, there are significant costs of various kinds.

I am not entirely sure who is intended to be target of this list, but given tradeoffs involved I think that it is unlikely that benefits are worth various costs. I would not recommend using cryptocurrency, at least as it stands now.

And costs related to cryptocurrency are significant and unexpected, for example:

• new exciting ways of losing money
• time investment is very significant and necessary to reduce the first one to acceptable levels
• significant increase of exposure to various scams (especially get-rich-quick schemes) infesting cryptocurrency-related sites
• reputation costs: nowadays it is safe to assume that mention of cryptocurrency is some kind of scam or swindle or scandal or lie. This one is the first one that I have seen in months that is not
• legal, especially tax related issues
• lack of regulation, laws covering various issues and system often explicitly constructed to make enforcement unfeasible
• typical use is insecure and has both cryptocurrency issues and traditional banking issues at once (buying BitCoin at an exchange)
• variable and massive transaction costs (20 euro for payment that is free if using regular bank is normal - see https://bitinfocharts.com/comparison/ethereum-transactionfees.html#3y though from what I see Monero appears to be much lower - https://bitinfocharts.com/comparison/monero-transactionfees.html#3y )
• significant external costs due to inherently energy-consuming proof of work, raising prices for electricity and electronics (CPU/GPU/SSD/etc)

and find it really useful for avoiding high international transfer fees

and it is yet another part about tradeoffs! For example I made many international transfers (sending/receiving) and never paid anything for that (within European Union + receiving transfers from USA). Once I needed new bank account (which was both less time-consuming and less risky than transfer using crypto).

It's a real shame that there are so many crypto scame, pump and dumps and shit coins out there at the moment, because many cryptos are based on some awesome technology, and have great potential.

Yeah, it is yet another case of evil people causing costs for others :/

Definitely, depending on use case and situation it ranges from "please stop, that is horrible idea" to "no alternative".

But right now it seems to me that median is on "please stop, that is horrible idea" or on "hmm, maybe, if you really want".
