Dont take anyones advice about what will happen with the currency, do your homework, learn about Bitcoin and come to a conclusion. Personally I believe we are just starting, but thats my own opinion and you shouldnt consider that as investment advice as well. You should figure out by yourself about at that moment, the price is good or it isn't. You have to do it by yourself cause you will not regret it if it's not success at all. Some people would like to invest their money into mining Bitcoin. For the past few years mining Bitcoin is only profitable if done at large scales. This means you will need to get expensive mining equipment and hopefully have access to free electricity. Also its usually much more cost effective to buy Bitcoins with this money instead of using it to buy mining equipment.
That is right. For the time being, it is better to save most of the coins and use the rest.
You're right, but the time you need it the most,much better to trade it if necessary you must be clever and active because its really important to sell it at the right time as if you wait longer then there is a chance that altcoin will simply disappear and that will be a big loss for you.
