One could say that we are in a price bubble and to be honest I think we probably are at this stage, however with that being said it's not exactly like the dotcom issue in my opinion. Bitcoin is in fact seeing mass adoption in countries such as Venezuela as well as rumours that it will start to be accepted by major eCommerce conglomerates such as Amazon. The dotcom bubble grew out of speculative or fad-based investing and many of these dotcom start ups never came to fruition. However with Bitcoin and other cryptos there is clearly future growth possibilities for them and if big business/ whole countries were to adpot it, the demand for Bitcoin would soar and thus the price as well. I then cannot see it falling significantly unless some catastrophic event occurs which then causes countries/ businesses to dump the use of Bitcoin / whichever crypto is being most commonly used at that time. Of course it could be overvalued during this initial growth phrase but just bear that in mind when investing and get in early. If you're on Steemit you're early. Honestly I'm not sure Bitcoin is going to be the crypto of the future but it is hard to predict. HOLDLN mine for a long time.
