History of BTC Price Increase

Quadrennial halving allows prices to rise.

The fourth halving of Bitcoin, a cryptocurrency that can be acquired, is expected to result in a price increase of over 410%.
※ The rise rate for this calculation is determined using the following formula, based on the 3rd halving cycle (from January 1, 2020, to December 31, 2023) and the 4th halving cycle (from January 1, 2024, to December 31, 2027): (Highest price during the period - Opening price on the first day of the period) ÷ Opening price on the first day of the period × 100. For the highest price in the 4th halving cycle, our forecasted value will be used.

Here are some of the joyful comments we have received

Customer Voice 1: Bought as a business expense, better than buying crypto. Works well and helps protect against inflation.
Purchased just before the end of the term.LLC Mr.T

We purchased Web3Maker® with our expenses because it was a period in which our company generated a certain amount of sales.
Since we purchased it in 2022, before crypto currencies were rising, it is now performing much better than the purchase price.
This product has helped me a lot because with direct purchases of securities, FX, and coins, I can't expense them.
I also think it is an advantage to have an asset that is resistant to inflation even if I am in Japan.

Customer Voice 2: Used Shirushi Coin to run several units. Started as side job, now considering it as a stable main business.
We are making it the cornerstone of our new business.Solo proprietor Mr.A

I have discovered a secret way to get a discount when you purchase Web3Maker® with SHIRUSHI Coins, so I have been using this method to get my machines up and running in my own way quite a bit.
My earnings from my main business have not been very stable, but recently it has become much easier thanks to Web3Maker®.
I would like to work on this as my main business in the future.

Customer Voice 3: Reinvesting earned coins into more machines. Flexible and sellable, with hopes for higher overall profit.
Compounding.Solo proprietor Mr.F

Web3 When I learned about Web3Maker®, I said, "This is good for compounding!" I decided.
As soon as I accumulate the coins earned by the machine, I use them to buy the next Web3Maker®.
Although the coin price fluctuates, I buy machines without worrying about the market price because I think the profit gained from the compounding effect will ultimately be more. Also, I can buy Web3Maker® directly with coins, so I don't have to exchange every single coin, which is very convenient.
