تفکیک بخش های یک سری زمانی همانگونه که پیش از این اشاره شد، یکی از اهداف ما در سری های زمانی، شناخت روند، تناوب ها، تغییرات فصلی و موارد نامشخص است. یکی از کتابخانه های خوب پایتون برای کار با داده های سری زمانی کتابخانه Statsmodels است. برای مثال استخراج روند، تغییرات فصلی و موارد پیش بینی نشده در مثال فرض زیر به این صورت خواهد بود.
import numpy as np from matplotlib import pyplot from statsmodels.tsa.seasonal import seasonal_decompose x = w = np.random.normal(size=100) for t in range(100): x[t] = x[t-1] + w[t] result = seasonal_decompose(x, model='additive', freq=1) result.plot() pyplot.show()

Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”
How to Invest in Bitcoin?
Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today? The majority of people that hold it are long-term investors.”
