Seems like a good idea on the front but remember this that in 2017 all these portfolio and fund groups made money, and in the following year ALL of them made huge losses. Many even the famous ones like Galaxy Digital, one of the biggest and most legit if I recall even made more than 50% losses. What does this tell me? I might as well just hold my own Bitcoin/Ether:)
This, assuming that this is not a scam of some sort this seems like the perfect situation for those traders, if they happen to earn money while managing the capital of someone else then they can keep a significant amount of the money they won on the markets but if they happen to lose then they take no responsibility and it is the investor that needs to absorb the losses, so as long as they can keep getting clients then they can keep earning money at no risk for themselves, to me it seems it is a way better option to just learn how to trade by yourself, I know it is hard and it takes time but once you do this all your profits belong to you and you do not have to share them with anyone as it is the case here.
this is not entirely true. there's a lot of cool people in the crypto world, that have their own communities, that their groups know they are trustworthy leaders: troy, wolf, dmitry, nick_core, mocho, scott melker, and the list can go on and on because there's quite a few established names.
it's those people that might want to use such a tool, because sometimes members of their community might want to copy trades they do, and this platform would make it easier to do so.
also it seems that you haven't really documented yourself about what the platform requirements are, because if you did, you knew that a group owner has to deposit collateral in order to get a group started.
there will probably be bad actors trying shenanigans at some point, but that's where the community comes in to act as a filter and weed bad people out. if the community does its job, the space might be entertaining.
also if i was someone new, interested in the platform, i'd obviously not mortgage my house and throw the money at random people over the internet, however, i'd stick around for a while, learn about the project, see how the community behaves, how the project progresses, how frequent updates happen and then when i feel comfortable, i'd throw 1-2 eth at someone i feel like trusting and take it from there.
or you can always start to learn trading on your own, that's also an option. I do have an interesting story about
How i lost 30000$ in the 2020 March crash that shows some of the emotions involved and how it affected my life. Maybe it helps someone wanting to take that path.
