just wondering how to determine the project won't die in the next few years?
I think it will be very difficult to be able to determine which projects can last several years. we can see that there are not many new projects that can survive in 2 years, even in the first year many of the new projects have no development.
Not that difficult to know projects that won’t die in the next 5 years, first you have bitcoin and ethereum, there is no ball of contention here, there is no need for further research on them, just believe it in your mind that whatever investment you have in this coins will forever be safe.
For other coins, it is also simple to know, first, you have to focus on coins in maybe top 50 of the coin market cap, and then you research deep into their product and see if they have a real working product.Secondly, you look at their past history and how much they have been performing, these are few out of many ways you can use to discern good project.
Theres guarantee that bitcoin and ETH will last more than 5years so investment in the coins are safe. Leave the doing research about the rest of the coins, selecting top 50coins on capital market, checking past history and how well the coins are performing in the market for the previous record don't count sometimes in the market which the new coins that claimed the top 50 on capital market have already justified that.
Knowing coins that will survive in the next 5years require simultaneously examination not a day or week research cause the crypto market are not stable and have you ask yourself why Bitcoin and ETH survive this long? It because the community/miners support the two coins and they can vouch for them for if it about TPS, have working product EOS,NEO,XRP etc would have the number 1 coin.
Mind you, every business setting where's support, trust and understanding will easily thrive. Remembered, what happen to Bitcoin when miners choose sides.
I can take holidays.
