In the future is the digital era, so that all activities are monitored and carried out digitally, including payments. Digital payments are currently developing, I'm sure in the future digital payments will definitely grow rapidly. Here the role of bitcoin can be used, bitcoin is a digital currency that can be used for payment. If bitcoin is adopted by many companies, of course bitcoin will dominate as a payment system in the digital era. Seeing bitcoin has a good development and has a system that is fairly perfect, so that in the modern era bitcoin will be needed as a payment system.

What motivates me to maintain crypto assets is the ability possessed by the coin itself in the future. This is very risky, but I believe in some coins that they can raise the price to the best position. Because he had done it before, like ETH and BTC. In addition, several other coins have feasibility, the prospects are also promising to invest.

if i see lately there are lots of altcoins popping up, especially in the digital world and whether for the next few years the function of real money itself will be eroded by the presence of virtual payment equipment ...? I had time to think whether in the next few years we would be making virtual money payments ...?

Their is the possibility bitcoin became a future currency. We are using some online wallet to pay a bill ,in future we will use bitcoin wallet for the transcation. If that happens, you no need to stay in a line to withdraw our money. The time to transcation will be very low.So the people automatically start to use bitcoin in future.

One big mistake that Nokia did was not adopting Android when it was obvious that Android will be the next big thing. Have they adopt Android and adapt with the market at the time, I'm sure things wouldn't be as bad for them.
It's a different story for Bitcoin. Bitcoin is continuously being developed by hundreds of developer all the time. It's an open source project, everyone can contribute to Bitcoin development. Also, why did you say Bitcoin is not the best? I believe Bitcoin has the most active development compared to other cryptocurrencies.

Cryptocurrency industry is open to all. There are people who got rich by investing in digital coins. The hype of cryptocurrency lingers few years back. For sure, there are politicians who can afford to invest big time have invested too. The hype brought them here.

We use paper money because its approved by the government to use and its effectivity compared to gold if in the early years we discovered the bitcoin/blockchain then I think its the currency we are already using right now because of its finite supply compared to fiat.

If everyone in the world gets into crypto and cryptocurrency will become an official global currency, do you think bitcoin then will stop depending on fiat currency? Or will it just co-exist with fiat?

I see that there are many ICOs that fail because of lack of funds even though the concept is good and potential, isn't it if the project is funded and realized the project will be successful and profitable for investors?

Look at the current cryptocurrency price movements which are always on the decline, might this be a factor for an investor to save his money first and wait for the cryptocurrency market to recover. And other than that, an ICO is very vulnerable to scam and might this is another factor for them to wait for the token to be listed on the exchange and if it does have a good potential they will buy the token.
