I see 2 types of social trading that may work for different people:

• User send his funds to brokerage, his assets are traded by portfolio manager "as is." The trades on user's account are basically carbon copied from trader's account; same execution, same leverage, Basically a "black box" strategy. Or a small hedge fund.
• Trader sends signals to users. It's up to the user to take or skip a trade, select exposure and leverage. There will be a delay between the time trader sends out the signal and user is able to act on it.

Both strategies have their pros and cons, YMMW. As I understand, eToro and ZuluTrade both offer the first version. They both operated as traditional (fiat) brokerages previously, added cryptos later as the asset class gained in popularity. eToro is registered in Cyprus, while for an odd reason, ZuluTrade is registered in Greece.

You can learn more about eToro's crypto and social offerings on the following links:

• https://www.etoro.com/trading/markets/
• https://www.etoro.com/trading/social/
• https://www.etoro.com/discover/people

ZuluTrade seems to lag behind eToro in terms of a clear overall web design, but here's a link: https://www.zulutrade.com/cryptos

What I would be more interested in is the second type of social trading. Following a trader's signals and executing the trade myself. I wonder if there is a platform for that. Or at least, is there a need, or am I the only one more interested in this type of arrangement?*

*I know what I'm doing. Or at least, this is my impression.

What other similar platforms are you aware of? How about a crypto only platform, not dealing in fiat? What are your experiences, both positive and negative?

This is quite a common feature on many forums. It would be quite useful for topics like this: https://bitcointalk.org/index.php?topic=1410577.0.

It is titled 2017 Bitcoin Debit Card Reviews and if I'm not mistaken it was last modified at March 24, 2016, 09:40:07 AM which is quite telling. "Community Wiki" posts are forst posts in a thread edited by the community and are supposed to be up to date.

Someone has been hacked: https://bitcointalk.org/index.php?topic=1546435.0

I've also seem to have been hacked. So I started a new life.

According to: https://www.owasp.org/index.php/Password_Storage_Cheat_Sheet#Use_a_cryptographically_strong_credential-specific_salt and: https://www.keylength.com/ I'm reasonable to assume I've used a strong enough password for this time and age - on a properly configured forum.

Password strength requires two components:

- The service provider to use appropriate password hashing schemes. See the OWASP.org link.

- The user to use a password of appropriate entropy for the time and age. See the KeyLength.com link.

If your user doesn't want to be hacked on your forum, how many bits of entropy should his password consist of, according to your algorithm and the rules of math?
