One of the main reasons a company opts to run an ICO is to fund development and business growth. The company will need to liquidate the funds they received during the ICO in order to cash in those funds. This can have a negative impact on the price of the invested currencies if the company floods the market. The impact of companies liquidating received funds on the market has been well documented. By allowing companies to receive up to 400 BTC during their ICO, it gives them a chance to realise some of the funds in the liquid BTC market rather than force them to sell STRAT into the STRAT market. This is designed to alleviate some of the impact that companies realising funds post-ICO could have on the STRAT markets.
