The rule that only accredited investors, which means people who are already wealthy, are allowed to participate in certain ICOs is senseless imo. It's like saying "YOU'RE NOT WEALTHY YET, SO YOU'RE NOT ALLOWED TO BE WEALTHY." Stupid society, with obsolete rules, we're living in.

If you mean that people cannot invest on bitcoins if they have no capital or budget because they are poor ? , they can always work on bounty campaigns here in this forum to earn cryptocurrency which they can use to start trading in the market.
