I have been a client, strategy follower and autotrader at Collective2 for well over a decade. I have tried other approaches over the years, but Collective2 is simply the best platform of its kind for vetting and following alternative investment strategies with your own money, and for autotrading those strategies at your preferred broker.Over the years they have worked with regulators, improved functionality, streamlined user experiences, and I have been impressed by their ability to keep everything very reliable in a complex environment where money is on the line and where that is not an easy task.Whenever I have had questions or minor issues, their support has responded within seconds, or, at worst, minutes, to help me out. They also refreshingly allow their more technical staff to be involved in conversations with users to answer more technical questions quickly.As with any relatively open platform, there are certain things (in this case, strategies and trade leaders) that most clients/subscribers would be well-advised to avoid. This is akin to low quality posts in any online forum, but the difference here is that, yes, you could lose money. Because of that, I would recommend Collective2 to people who are willing to take responsibility for their own actions and choices and do their homework on which strategies they follow. For example, I wouldn't personally allocate my money to a strategy until I first at least had a message-based conversation with the trade leader, and made sure they had sufficient history and transparency in their methods such that I was comfortable with what I was getting. Far too often in the investing world, people will blame the platform, the strategy, their broker, or anything else they can find, in order to convince themselves it wasn't ultimately their own decisions that caused a loss.There are some excellent strategies with positive long term expectancy and low correlation to buy-and-hold market performance on Collective2, which is why I am still here after all these years and valuing its role in my investing life more than ever. This is typically expensive and hard to find in the investing world, and usually prohibitive to anyone who is not firmly in the "high net worth" category or higher. Collective2 offers this at an unmatched value and with easy, flexible implementation.I felt the need to write this since I see many reviews where a customer clearly joined, greedily rolled the dice by choosing to follow a questionable strategy with too much leverage trying for a "get rich quick" outcome, and then blamed the platform when it didn't work out for them. These reviews are simply not worth your consideration other than as a reminder that any tool can be used incorrectly if one is not qualified to use it.If you want a platform that will put you in a bubble with guardrails and tell you what to do, Collective2 is not for you. If you want an ability to access excellent strategies that provide top notch diversification benefits to a traditional investment portfolio in an environment that also happens to contain some not-so-excellent strategies, if you resist shooting yourself in the foot with short term over-leveraged greed, and are thoughtful about your decisions, then you will be thankful to be a member of Collective2.
