We can't guarantee investors get a return because the market will decide this. However the total token supply is 5 Million. The 2 Mill tokens reserved for the Token Crowdsale (including bounties) will be distributed 2 weeks after the crowdsale and will receive quarterly payments (ETH) based on the profit of Ethbits Local. Ethbits local will be launching in many countries around the world - we have this arranged already. Unsold tokens will be burned.
Also the remaining 3 Mill tokens will be locked in multi sig Escrow until Ethbits iTrade launches and even then our minimum price for the sale of part of these is 1 ETH.
I hope this answers your question.
