Why did the bit coin division upset occur?

Beginning of a 1-bit coin division trouble
Bit coin is
1, remittance is fast
2, the commission is cheap
It was a merit.

However, a lot of people using bit coins have increased, and congestion of transactions has occurred.
Due to the increase in trading volume, the remittance speed increased and the user wanted to remit money quickly, so I had no choice but to charge a fee.

The bit coin trading volume of the day is 250,000 transactions in the world.

As an example, the transaction volume of credit card Visa or MasterCard is 600 to 800 times the bit coin.

There is still much room for the development of bit coins.

However, unless this problem is solved, it is difficult to expand bit coins.

2 Solution
① Increase the capacity of the bit coin block saving the bit coin transaction record
→ This increases the processing capacity of the transaction and increases the remittance speed.
② Increase the processing speed by preparing another sub chain without changing the block size of the original block chain
③ Do the Segwitting
→ those that reduce the amount of transaction information to be stored one by one
④ Segwit 2x
→ Reduce the amount of transaction information and also enlarge the block

result
Segwit 2x was introduced
