Question for discussion:
Should exchanges be allowed to harvest?
Should exchanges be allowed to harvest?
You can't stop anyone from harvesting. Each account makes it's own decision
It's their call no one can stop them. Although I must say I wouldn't do that...
If they really do, I hope they're doing it on some separate node, not on the node they use for getting information.
People hate banks for the profits they make off us but I guess it's ok for exchanges.
Well, this is a problem.
Many people send to Poloniex and increase her PoI. Already at 10%, no way to avoid this, ok?
it is possible attack the network with a significant amount of PoI?
It's always a bad idea to leave your crypto's at exchanges for more time than you need to. People should know this. See my signature and you know what I mean.
I lost that amount in Bter.
No it's not a necessary evil. Why would it be necessary for anyone to leave any coin on an exchange ?
If you want to sell something deposit the amount you want to sell on an exchange. Keep the rest in your wallet.
It's really baffling that people still keep coins on exchanges. How many compromised exchanges does it take for people to learn ? I guess always 1 more.
you should ask the question why people let her coins on exchanges!!
Because it is easier, and because people do not want install additional software, and also because an exchange can be accessed from everywhere.
That's why NEM would be a step forward to the others with a secure, easy constructed and accessible online wallet
