Bitcoin of today is useless because of slow speed and high transaction fees..

But do you know that TCP/IP of today had some serious technical issues with security back when the technology was under development (just where bitcoin is today)

Check this the below research paper on TCP / IP that highlights the security problems in the TCP/IP protocol suite (written around 15 years ago), where the author focuses on protocol level issues, rather than the implementation flaws... The paper "Security problems in the TCP/IP Protocol Suite" was originally published in Computer Communications Review, Vol. 19, No. 2, in April, 1989.

If you give this a read, you will never call BITCOIN useless:P

Bitcoin of today has several issues with speed, number of transactions and the transaction fees, BUT price is high because the world still wants BITCOIN TO BE THE REAL KING OF CRYPTOS in future, and are putting their money for the FUTURE BITCOIN
