I probably not very lucky with buying coins)) As an example, I bought litecoins when it cost about 25$, so I was waiting, waiting, waiting and the coin didn't  go up)) So, I sold it. Next day, maybe the day after the next day, but it jump up to 45$ approximately) Again, I bought it and began to wait, I guess, I was not patient, so I sold it again   Of, course, after that, it went up to 90$ +-
I decided not to waste my time to this coin, so invested in bitcoin. Here  I was more luckier, maybe more patient and was rewarded with a good profit in December  

But I do not give up, I am still interested in this subject.

Because of the bitcoin's instability (there are so many different "expert "opinions about it, but nobody really knows what will be with it tomorrow, imo) I've decided to try my my luck again and to take a look for other alts.
That's why I came to this forum, to get more info, to learn more about it. Who knows, maybe I find something interesting to invest in it))
