Re: Someone is spamming the blockchain

Curious as to why they would use 300 BTC for an experiment when 5 would do the trick just the same...

Because it wouldn't do the trick just the same. If they are sending transactions just a few blocks apart, then 5 BTC wouldn't be able to be sent without a fee. Remember that a fee is required whenever Bitcoin * Days is less than 1. 30 minutes * 300 BTC = 6.25 Bitcoin Days, but 30 minutes * 5 BTC = 0.104 Bitcoin Days.

Ah that makes sense as to why 300 BTC then - nicely pointed out

[EDIT] but yeah - why not 50 then?

If they want to do it every 3 blocks, they might want to make sure the transactions won't have trouble getting through in case 3 blocks are mined rather quickly after each other. Or, they just had 300 BTC handy that they didn't want to split up. Or.... ??
