1500BTC minimum would be quite hard to achieve given the high rate of bitcoin.Also people like to diversify their investment portfolio so they do not put all their eggs in one basket.I think the minimum limit should be adjusted with high bitcoin price
@zahra4577: We think 1,500 BTC is fair and necessary to develop the features we're looking to build. It may be adjusted slightly if BTC takes a sharp turn upwards, but at this point, we will keep it at 1,500 BTC.
