Hello everyone, I haven't been on the forum for a long time, but now, in my opinion, is a good time to look around what is happening, and if you go into projects, it's better in the early stages .. maybe  they will give a good profit

2017 was a big year for ethereum and majority of the ERC-20 tokens. Further there is no big growth, the market kept crashing. None expected such a huge loss in ethereum value falling low to $100 from a value close to $1500. By those days bitcoin too experienced a great fall in its value. Later when bitcoin started to pump high ethereum was the same without big growth. Hope 2020 will be big for ethereum.

You did it right but it was only a part. The most important thing in this market is the market condition, uptrend or downtrend. If a project is solid, in a market downtrend will still face many difficulties, and you will still lose your investment. So choosing the investment time is still the most important.

Each investor is responsible for his actions himself. but if the project could not fulfill its promises and raise the necessary amount of money or could not realize its model, then the responsibility lies on the project and they must compensate money for investors

I am really curious about this question. To be clear, if there would be an opportunity to sell your tokens and make x5 right here and right now in exchange for promise to never invest in crypto again. How many people are ready to sell their tokens/coins at the moment and never come back?

No need for new projects anymore but still people coming with them everyday so you need to stay away from new projects because none of them going to last long for even a year.

Both still focus on token purchase but the different is instead of the developers dispatching the coins, they give the tokens to the exchanges who will dispatch the tokens to investors.

One thing for sure is that; IEO do not  guaranty that a shitcoins will not go down the drill when the time comes.

The con there is that, (1)  investors will be free from scam developers who intend to steal from them.
2) Avoid littering their identity info through KYC in different websites. Since the exchange already have their information.

3) Since an exchange already have the token, listing won't be a problem. And also you get to choose on which project to invest in since many developers ends up listing coins in exchanges which are not even worth it.

If the token you intend to purchase is listed on Binance, you can take it as an additional plus. *Yet, it's not a guaranty that the coin will survive in the long run.

if I think personally a safe way to invest in cryptocurrency is :

1. the project runs according to the roadmap and whitepaper that has been made;
2. cryptocurrency that we invest in already has a product;
3. the team always updates about the progress that is happening in the project that we invest;
4. invest in project that are in the top 1-500 in coinmarketpcap (have a high volume);
5. the project we want to invest has been running for a long time (if I personally never invested in a new project), because investing in new project has a greater risk than we invest in old project.

Its indeed has a huge impact on people, it makes them more afraid because of what they had experienced and we can't blame them because it happens on most of us too. Most of them are not willing anymore because they think they are falling again into some sort of scam, you can literally find them everywhere and that is the reason why we need to be very aware and careful.

Is a centralized or decentralized network better? How to develop the authentication feature and ensure it works well? What innovations need to take place?

At its peak in late 2017, one Bitcoin was worth nearly $ 20,000. A year earlier, it only cost $ 1,000. Bitcoin was priced at $ 6,000 in June and $ 8,000 in July and dropped to $ 6,000 in August. Bitcoin price is extremely volatile, so does Ethereum. According to the Dacxi crypto social network, unlike the pioneering wave, the next global growth wave could be fueled by two new areas of investment: institutions and retail investors.

So whether or not cryptocurrencies grow will depend greatly on the understanding of the future community. And what do you think about this?

Government regulation is indeed needed to prevent fraud in the cryptocurrency market. Too often, scam projects have a negative effect on market confidence and also new projects that should have the potential to develop in the market

Still yet to know what Justin Sun got to offer as regards the upcoming news in few days,  but I believe Tron is worth to invest in,  it might do another Xrp in future in terms of its price
