OP, for myself I'm going to rephrase your question to 'why you support crypto startup investment?' Well there are a lot of scams and deception in the ecosystem but its a fact that blockchain and cryptocurrency technology is a gold rush. With the uncountable number of great startups idea out there facing serious difficulty in accessing funding, discovering that they can easily raise finds if they align their to blockchain will naturally attract them. Thus both the good and the bad actors will try to raise money through this medium.
