I always keep new coins if I do not have the funds. More often it happens that keeping coins for more than one year is necessary, because their price, for example, is very low after entering the stock exchange or the project team has not yet realized all the plans that they have claimed in the Roadmap. And as a result of these plans, interest in the coin is growing and its price also begins to grow.

Naturally, before investing it is necessary to study as much material as possible about the project and reading White Paper is one of the important points. Although I can say that I invested in two projects without reading their White Paper, but they were both successful enough. I met projects with a well-written White Paper, a good idea, but they did not succeed. I think that to select a project for investment, you need to look at a lot of things, for example on mentioning in the press, to study each member of the team, to look at their social pages, if possible, to communicate with them. Openness of the team is the first sign of trusting the project.

I invested in Life (i don't know if topic is created about this altcoin) and i really believe in this project.
Maybe i'll made a topic for a presentation about Lifetoken.
But in 2 years so many will change.
Maybe one BTC can go to 100k$ ! 
The future will be amazing!

I, too, half a year ago invested part money in the Life coin, I liked their project and team. Now this coin is cheap and has great growth potential, so I support the opening of a new topic, I will be the first who will join you

Yes, more and more institutions are starting to accept crypto currency as payment for their goods and services. In Ukraine, the city of Kiev already has many restaurants, a whole chain of restaurants that accepts Bitcoin, Dash, Litecoin and other crypto currencies as payment. And there are more places like this every day.

You can look at the TRM token, having which you will receive dividends in the form of Ethereum on your wallet. This token is a kind of share in the current business, which consists in the mining of cryptocurrencies.

Investors looking to venture into the cryptocurrency market may want to set their sights on buying alternative crypto assets as opposed to just buying Bitcoin. Bitcoin is coming off of an all-time high of just under $20,000 and currently trades at a price of $8,200. Should Bitcoin return to its previous all-time highs, investors that purchase today will receive an ROI of 140%. That's not bad if you're comparing this return to the average returns in the equities market, for example.

But there are many other crypto assets that have the potential for greater ROI should they return back to their original all-time highs. Investors may want to take a closer look at Ripple’s XRP, a blockchain solution that has the potential to revolutionize the banking system as we know it. Currently trading close to $0.70 coming off on an all-time high of just over $3.30, XRP has the potential to gift investors with a whopping 300% return, if the asset makes its way back to its peak. It’s very well possible!

Zcash is actually quite a popular coin and it is traded on many exchanges, the coinmarketcap on the Zcash page has a list of all the exchanges on which it is traded, at the moment there are 100 of them. I will leave the link so that everyone could read: https://coinmarketcap.com/currencies/zcash/#markets

This price is achievable as a result of the fact that 10% of offshore accounts will be in Zcash? Sounds good, of course, but so far this is only a guess, albeit pleasant for all holders of Zcash.
