Bitcoin (BTC-USD) commenced trading at $83,624.79 on Wednesday, September 30, 2026, showing minimal change from Tuesday’s opening price. By 7:17 a.m. ET this morning, the value of Bitcoin had risen to $83,767.
Ethereum (ETH-USD) opened today at $2,676.74, reflecting a decrease of 0.4% from Tuesday’s opening figures. By 7:22 a.m. ET, the price of Ethereum had risen to $2,686.56.
Both Bitcoin and Ethereum are striving to regain the record levels they achieved last week, yet they are keeping major monthly gains intact as September comes to a close.
Achieving monthly gains in September has historically been challenging for Bitcoin. Data from CoinGlass indicates that the trend of “Red September” might finally be reversing:
From 2013 to 2025, Bitcoin closed September in the negative eight times out of thirteen years, with six consecutive years from 2017 to 2022. Despite this year’s increase, the average September return remains at a dismal -2.34%, according to CoinGlass data.
However, the tide appears to be changing. In 2023, Bitcoin ended September with a 3.91% increase, followed by 7.29% in 2024 and 5.16% in 2025. This year could mark the longest positive streak for September, making it four consecutive gains.

Cryptocurrency and Taxes
Generally, you incur a tax liability when you exchange cryptocurrency for a profit. This rule applies even when swapping one digital asset for another, such as converting Bitcoin to Ethereum. The IRS does not view this merely as a trade; any change in value is considered a taxable event.
Taxes on cryptocurrency are not paid immediately; they must be reported on your tax return for the year in which the transaction occurs. Thus, if you make a profit selling crypto at any point in 2025, this must be declared when submitting your 2025 tax return in early 2026.
The tax amount you are responsible for typically depends on two key factors:
-
The duration you held the asset before selling it
-
Your total taxable income and filing status
If you hold a cryptocurrency for under a year, you’re generally subject to higher taxes. Conversely, holding for over a year usually results in lower tax rates.
This distinction regarding how long you hold an asset can significantly impact your tax obligations. A difference of merely a few days can potentially alter the tax rate by 17% or more, so timing is critical.
