I got one for like $35 on ebay a couple weeks ago, seems its only worth around $18, should I sell or trade it or just hold on? Im starting to believe only BTC has the true potential, seems a lot of these altcoins wont make it? Thoughts?
The same thing has happened with the price of bitcoin though as well.... so in that regard whats the difference. The drop in value or rise in value might not be exactly the same but they are still pretty dang close.
Here's my take on alt coins though. Even though Bitcoin is still very speculative imo there is a least some valid reasons for more people jumping on board such as more and more merchants lining up to accept it, more and more VC's pouring money into start ups and infastructure, and it becoming easier and easier for regular people to use. With altcoins thats not the case so you could argue that altcoins are waaaaay more speculative than bitcoin. I person dont know of merchants lining up to accept altcoins as payments. If someone asked what had more potential in coming a "big" thing I would say bitcoin certainly is leading the pack, but also it's hard to predict the future.
I think one major benefit in altcoins would be if something really bad happened to bitcoin la lot of people would instantly fall back on altcoins and that would be good for them would be good for them. In the case of something like litecoin I think it's worth noting that both the creator of ltc and his brother are both heavily involved (in one case the ceo) of two of the largest bitcoin related companies/exchanges in the world right now. Because of their vested interest in lightcoin and their connections/power in the crypto currency would you could certainly assume they will have a valid reason and an ability to push something like litecoin a lot harder in the coming years.
As far as weither you should "invest" something. That's totally your choice and only you can answer that. I don't know your finincal situation but typicaly if you buy something and only a week later you're thinking about selling it you either 1) invested more money than you were willing to actually lose or 2) you were looking for a quick buck and not really thinking about long term potential.
In my case I own some LTC. When I made the purchase I asked myself "If I had this money in my pocket today and it fell out of my pocket would impact my life or cause a lot of stress for me aside for being angry/sad for a few hours that I lost it". When the answer was no I went ahead and purchased those LTC and in all honestly I haven't even checked the value of LTC since then and wouldn't even begin to think about it until decades down the road. In my mind that money is already spent and gone and i'm not worried about it regardless of the outcome.
Hope that gives some helpful insight, just my personal views and by no means am I an expert or anything.
