Every great thing has also some disadvantage. Though there is no doubt that Etherum is the great coin, it has also some disadvantages. Which has been given below:
- Slow transaction speed
- Hackers can hack it's wallet if people don't aware.
- Ethereum is currently capable of handling about 5 transactions per second which is not suitable for the global scale projects. Because there will be more big big project soon.
- Though transaction fee is less now, it will increase soon due to overload.
I think these are the main disadvantages of Ethereum.
Thanks
