Kinda tempting to invest.
What is investors guarantee that your not gonna run away with our funds?
Can you provide reviews from Bitcointalk member that they successfully invest and got returns?
It will make your crashbot more reliable if you will be able to provide reviews.
I don't think that prior reviews are going to guarantee you anything.
Look at Cryptopia for example... no one had lost money by depositing to them until one day a lot of people did lose money!
Personally testing something with small amounts is usually the best strategy (aka "testing the waters").
However, be aware that even in those cases there are some scam services
(I'm not talking about CrashBot here) which will operate normally and reward users with small accounts and when someone deposits a bigger amount they lock their account. This is a usual strategy of scam exchanges.
