But don't you think it is quite easy to go around this new policy? If somebody wanted to donate cryptocurrency to a particular candidate or party but cannot because it is prohibited, then he/she could just easily convert his/her crypto first before donating it.
That's the whole point of the restriction, identifying the donor.
Or if somebody from Russia is instructed to make huge donations to a candidate they are supporting, isn't it easy to channel such fund through another person from Ireland?
There are limits in place, you will need to find a lot of people to donate small amounts, and when a lot of them do it is easier to trace where the money is coming from, one or two transactions can get unnoticed but when thousands of people suddenly start receiving money from abroad and donating for the first time it gets suspicious.
With crypto donation it was simple, you could donate millions in 10$ batches from millions of addresses anonymously.
Plus, political parties and candidates have to reveal how much they've got, cryptos allowed them to bypass this and use money from donations for themselves.
