Lack of regulations - Despite the fact that governments are doing their best to regulate this space, it's still in its initial days - Limited controls can without much of a stretch permit anybody with a ton of property to control the market.
Lack of institutional capital - Banks and other foundation are available to blockchain technology however haven't contributed, yet, a lot of cash which would mollify the unpredictability.
They have no intrinsic value - Regardless of some other organizations, cryptocurrencies don't make an items, acquire income, utilize a large number of individuals or even return dividents - Because of this is it extremely difficult to esteem them, we frequently depend on advertise assumption which is affected by the media.
Agreed upon the points of lack of regulations and lack of institutional capital which will happen in due time. BUT i couldn't disagree more on the point of having no intrinsic value, as cryptocurrencies are not suppose to make any item because it is the outcome of the Blockchain which is the item. And as far as dividends are concerned many new ICOs are paying the dividends like Bankera and many more.
And as far as the value is considered i can give you many examples of currently available financial system which itself has no value like GOLD, SILVER or as a matter of fact any currency.
Its all about demand and supply of any currency, commodity, cryptocurrency and people willing to take it as a payment in exchange of goods and services.
