I am not know much of detail of bts, I don`t if change the base parameter like block interval ,MIN tx fee,there must a hard fork, I don`t know if it is available to change the base parameter of bts by all bts stockholder to avoid hard fork as follow process
1. everyone can create a base parameter vote by spending not little bts, like 5000bts, to avoid there are not many change proposal to increase the load of stockholder.
2.if this proposal can get 51% vote of all stockholder in period ,like 60 days. block change acc.to this result ,change the base parameter automatic.
Actually the different change of pow coin can been consider the base parameter change by imformation of blockchain.
so I think it is less risk by developing this function.
