Money laundering by using bitcoin is a main concern in many governments and that is a major reason countries like India, Sri Lanka, China and other countries have already warned people about the use the cryptocurrencies and there are some countries who have already banned cryptocurrecies entirely inside there countries so what can we do is to show the good side of bitcoin more and as users we can do more to eliminate bad use of bitcoin and which is a difficult think to do but if we want governments to accept this should be done
