Moving from Unstable to Stable is the Dream of Humanity. Let it be a business, a career or an income for instance. Everybody loves the word stable. It wouldn't be fair to exclude cryptos for that.
The Intraday concept has been in practice in trades of all kinds let it be stock, forex, commodities or cryptos. These fluctuating results in existence of N number of unstable coins. But it can fluctuate the exchange rate for stable coins.
Cryptos for instance is imaginary. It cannot be realized physically like we do for Fiat Currencies. Because of its flexible Nature, anyone can produce it easily by various Methods of Mining. On the other hand, one disadvantage is with unstable coins because nowadays, many have come up in the market with many features we do not know which would survive in the longer run and which is the best.
The word stable is required in most cases such as career, education, business etc. without stability all the above activities would not function to their maximum capacity. Because of the competitive war. The same logic applies to crypto coins as well. The best stable coin you own, the Good Value in the market and stability.
In my opinion the best stable coin would be that crypto which is more user-friendly to you. Forget about the market value. There are no worries for cryptos being lost or missed away, security comes first than services.
The longer you mine cryptos over a period of time the value and stability are the future prospects of such coins and are stable coins. The vast transactions and usage of any cryptos make more stable and reliable across communities to involve in daily transactions and acceptable worldwide.
