Sorry i'm a beginner.
But later,can we exchange EagleCoin to Bitcoin?
No never, keep them for 7 years then exchange
Dont listen to him
In most of the cases an exchange will pick it up early like Yobit or Bleutrade and then you can exchange for BTC. Most of the time better coins end op on larger exchanges. The ultimate reason for alt-coins to exist it seems is to try and create an alternative to BTC that could improve on its weaknesses and implement new innovation that is not easy to do with BTC and eventually come up with the ultimate digital coin to take the world forward. Because you are a beginner (n00b), I will give you the following advice to survive in the alt-coin environment:
1. Do not listen to most trading advice because 99% of alt-coin traders will sell their mother for $5. Most advice will be to get you to be a sucker so that they can quickly make their profits by exploiting your n00bness. Trust your own gut and instinct.
2. Do not keep coins long but rather get rid of your coins as soon as you can make a profit or in some cases when you can limit your losses. There are exceptions with perhaps a handful of coins that will put you in the green over the long term but those are rare and do extreme research to identify those.
3. Look out for traders that do give out good advice because there are those although they are extremely rare. At the same time, learn which BCT accounts including hero and legendary accounts are just shill accounts or members of pump groups and do the opposite of what they say or sometimes knowingly ride on the back of their advice to quickly make a buck on the up and get out before they dump large numbers of coins on unsuspecting n00bs.
4. Rarely listen to anything in troll boxes on exchanges because those advice are most of the time from bag holders/devs/pump groups that shill the coins they want to dump to make profits by selling to n00bs like you.
5. Do not invest any money that you have not already written off as lost.
6. Many new coin launches are scams since it is very difficult to identify devs and to determine if devs are legit, sincere and committed. Most of the time scammers hide behind newbie accounts and then disappear. Many people with "new money" like you have been burnt by believing hype and being taken for a ride by scamming devs.
7. Alt-coins is high risk high reward. it is possible to make a lot by taking a high risk but you can then also lose a lot. Depending on your risk profile it is sometimes better to buy established coins that have a proven dev team that have been around for longer than a year, but then your profits will also become less most of the time.
Based on statistics in alt-coins, the typical thing that happens is that a coin is launched by a newbie dev, then an exchange picks it up, then it is shilled then it is dumped by the speculators and then the people that did not dump early become bag holders and everyone moves on to a new coin. I am not saying this is hat will happen here but it is important that you know how the typical new coin works out. Therefore, be very meticulous with your research before you put any money into any coin. Most of the time, get in and get out quickly and play with small amounts. If you want, you can be prudent and apply rule 1 above to this post also
