4 reasons why cryptocurrency is still an unpredictable bubble

1. The cryptocurrencies are subjected to fraud:

Since they are unregulated, there is a high chance they can be subjected to online frauds. They haven't yet found way to exchanges. In fact, since the nature of the transaction of these currencies is encrypted, there is a high chance they can be used for illegitimate exchanges.

2.Demonetisation fear:

The demonetisation of certain notes in India have made many skeptical about the digital currencies. There is no surety provided by anybody and they can't be exchanged easily with traditional currency. So this fear still rules in the minds of many.

3.Uncertain price fluctuation:

Nobody can give a guarantee that bitcoin investment can be profitable. It is a very volatile market. Seniors won't bet on such currencies.

4.They cannot bring uniformity in currency:

Had the idea of John Maynard Keynes about bringing all the world currencies to same level, the digital currency could have become more successful. But such is not the case and it will take many more years for all the countries and currencies to come in equal levels
