You can not mine cryptocurrencies easily with a simple apps, those apps are all scam and they wont give you what they promised!
To mine BTC you need either a GPU (graphics processing unit) or an application-specific integrated circuit (ASIC) in order to set up a mining rig. And this is not something that an app will offer to you for free!
Be aware of Scams.

Sure. Why not? Gold or other precious and or strategic metals which have intrinsic value,are a store of value and used as currency if needed so.

Although a retracement from its recent highs seems plausible in the short run, they expect MATIC to reach new highs, triggered by the increased investors' attention, and climb up to $10 by the end of 2021. MATIC could be a profitable investment in 2021 and beyond.

Not currently, no Lets count:
Medium of exchange. The main criteria for something to function as a medium of exchange are that it be robust and portable, Since BTC are virtual, they obviously fulfill these functions.

Unit of account. A unit of account needs to have a stable value. Here's the value of bitcoin over the past year:

Store of value. Look at that chart again what happened at the end of December last year?

People believe Bitcoin may come to serve as a unit of account and store of value because its supply is guaranteed to be stable. This depends on believing that the demand for the item in question is stable, which clearly currently it is not. As a matter of economic theory, I do not personally believe the demand for money is ever stable, and therefore the whole theory on which Bitcoin is based is false. However, that is clearly a more controversial point.

You are right sir, to be sincerely they have used all this chemical to destroy some body system of people may God help us we just have to be careful with our health  because health is wealth.

Let’s be clear. From what I can see, it’s the company and not the platform whose name is changing.
I believe that it’s because they don’t want their name and branding tied only to one of their platforms - especially as they gain more assets under their umbrella.
I hope this makes sense.

To my my own knowledge and what i really discover we need to be more sensetive because  if everyone looked after their unique microbiome , and STOPPED eating processed foods , thats fast foods, manufactured foods , sodas , colas , the products the food industry sells us as good is actually damaging you. if its advertised its chemicals wrapped up in pretty packaging making a huge profit, real foods , they grow, herbs , nuts seeds, eat as much as you like of whole foods, - stay away from sugars and anything with a list of ingredients you would not have in your kitchen. FEED your immune system - feed with as much variety of healthy organic or permaculture real plants and real food - look up about microbiome- read prof Tim Spector, spoon fed .

I don't believe someone can ask this on bitcointalk, it funny but bro kindly type it in Google that will surely give you final answer.

Altcoins and NFTs, without a shred of doubt.

We have entered the age of digital transformation and the digital economy.
Boomers were able to get rich by simply buying a house in the 80s and sprinkling their savings across low risk stocks, which netted them a 45x.

Now, crypto was the chance for us get rich with a 100x in Bitcoin since 2015 at $500, another 100x for those who invested last year and probably another 50x for those who invested this month.
Everything is digital now.

Don’t get left behind.

I really agree with you as a newbie i  learn something in this forum that in respective your rank once you do what is against the rule and regulations of this platform you must deserve your punishment. Sometimes i read some topic in this forum without making comments to add some knowledge to my understanding including people comments to avoid making a mistake in future.

Blockchain the safest and most popular wallet. It is used for investing and storing cryptocurrencies. It is one of the most secure Bitcoin wallet which keeps track of who owns the digital tokens.
