I am not totally worried. But at some point during the big drop I almost sold my coins. I spent a day thinking and calculating my losses in case i sold them that day. After a day of thinking I came up with a decision to just hold my bitcoins and store it first in hard wallets, until such time that the prices will rise up and keep my losses to a minimal that is the time I will decide to sell my bitcoins. Let's all face it bitcoin technology is slowly degrading with the slow transaction and high rates it will slowly loose it's value as some people will look for other alternatives that could compete with bitcoins. If ever bitcoin technology will improve in the coming years then bitcoin will still be the top cryptocurrency. Even today bitcoin is still on top even though there are a lot of issues in transaction and fees. Once I keep my losses to a minimal state then I will start thinking of other alternatives.
