Diversity, that's why. Sure we all are making good money from bitcoins. Sure the price of bitcoin is going up. But is it going to continue to be that way. Are ICOs going to continue to be successful? A lot of ICOs are coming in and it's only a matter of time for big gamers to come in and ruin this whole opportunity for us. Thinking about banning bitcoins, bitcoin isn't the only thing that's going to get banned if the government is going to try and take over. Today, a couple of major countries have already banned participating in ICOs. I guess they are just trying to protect their citizens from getting financially scammed or something but it's still doing things. Last time I just saw an ICO that doesn't allow US citizens to participate because it has been banned by the SEC. If the government truly is powerful, they will be able to ban this whole crypto thing or atleast do some damage against it.

Once the whole cryptoworld is taken over by the government, where are you going to get money from? Obviously you can't say crypto. Plus, it's also good to have a business that will allow to feed your family and buy things so you don't have to spend your precious bitcoins.
