استفاده از Enumerable ها همیشه هم خوب نیست، یک برنامه نویس باید بدونه کجا باید از Enumerable استفاده کنه و کجا باید به استفاده از اون خاتمه بده، در مثال بالا تا زمانی که یک کوئری از Enumerable رو ToList نکنید، هربار که روی اون پردازش انجام بدید مجدد فرایند کوئری ها اجرا خواهد شد.

n the U.S. people generally use Bitcoin as an alternative investment, helping diversify a portfolio apart from stocks and bonds. You can also use Bitcoin to make purchases, but the number of vendors that accept the cryptocurrency is still limited. Big companies that accept Bitcoin include Overstock, AT&T and Twitch. You may also find that some small local retailers or certain websites take Bitcoin, but you’ll have to do some digging. That said, PayPal has announced that it will enable cryptocurrency as a funding source for purchases this year, financing purchases by automatically converting crypto holdings to fiat currency for users. “They have 346 million users and they’re connected to 26 million merchants,” says Spencer Montgomery, founder of Uinta Crypto Consulting. “It’s huge.”

That means the future is ready to move in.Likely, there will not be a wholesale shift. Company actions will aim to benefit from economic growth, inflationary pressures and a return of market-determined interest rates. In turn, all of that should drive the stock market and investment returns higher.
