!!! BE CAREFUL WITH GRAVIUM COIN !!!
If you no longer believe in DSR, sell it for BTC instead of swapping it for Gravium or you may lose all money. Gravium's dev will sell your swapped DSRs for BTC instead of 'burning' it. Why do you dare to swap a coin with real value for a coin with no value (at least for now)? Gravium is a new coin, nothing is sure about its future. DSR is still being maintenanced by lazy_boozer. Again, if you no longer believe in DSR, sell it for BTC. If you would like to invest in Gravium, buy it when it is listed on exchange.
