Suggestions: That's why I think you all should be careful about bitcoin trading and focus on Altcoins when you are expert.And must avoid HYIP investments and go for earning bitcoins without taking high risk.One day you will know what actually means about success.
I agree we must do research and study the market well. Even in a Bitcoin market we should familiarize ourselves in trading, the signals, charts, news, hype, and FUD. This indicators can tell us where the price will go. As of altcoin, you should never trust 100% any projects may it be old or new. We should also keep ourselves updated and always set up stop loss so that whenever the price of a certain altcoin we are trading goes down we can sell them at a reasonable loss.
As of the HYIP, I always avoid that scheme. It will highly not give us a good result, may it be with friends or money.
