(or even 6-8 confirmations it depends the service you're using).
Normally those are for involving a larger amounts of payments.
Payments with 0 confirmations can still be reversed! Wait for at least one.
One confirmation is enough for small Bitcoin payments less than $1,000.
3 - Enough for payments $1,000 - $10,000. Most exchanges require 3 confirmations for deposits.
6 - Enough for large payments between $10,000 - $1,000,000. Six is standard for most transactions to be considered secure.
60 - Suggested for large payments greater than $1,000,000. Less is likely fine, but this is to be safe!
I am sorry UserU but this is not true and it's a bit dangerous to say.
A malevolent user could split a payment on 10000$ in 10 or more micro payment and this will not avoid a double spending or any type of protection.
As I have told it depends the service that you're using since there is any standard related USD$ amount, and
https://www.buybitcoinworldwide.com/confirmations/ has just provided some suggested limit.
There is any connection between FIAT equivalent that you are moving in btc.
Just as E.G. as I have just explained:
https://support.kraken.com/hc/en-us/articles/203325283-Cryptocurrency-deposit-processing-timesKraken accept a deposit after 6 confirmations (around 1 hour) independently the amount you are sending to this exchange.
For example, on the Bitcoin blockchain, a block is mined on average every 10 minutes, and Kraken only credits Bitcoin deposits to a client’s account after 6 confirmations, which takes approximately 60 minutes.
However, sometimes it can take Bitcoin miners 30 or even 60 minutes to mine a single block (1 confirmation). This is outside of Kraken's control.
or Houbi accept:

As you can see depends from the service that you're using and this is not linked with amount of money that you're using (we are trading bitcoin not fiat, it means that in a crash pump or dump these limits become totally non-sense) .
