because everything can be happen with it,
it's because of the project lack an attention from people or regulation or even because of the exchange itself.
i think,
it would be better for you to keep your Bitcoin until you understand how it works.
compared to other,
Bitcoin is much more 'stable' and 'reliable'
I agree, but I have to put a definition on the word safety, especially in this market, then I would go for those coins that can be invested upon with less chances of losses. Then, I would say go for Bitcoin, as the primary medium, because it's the best coin in the market. It's that simple. The price, the marketability, the support it commands and all other positive contributory aspects an investors wants to see in an asset is more or less held by Bitcoin. So again, that is premised on "safety", which is virtually non-existent in this market, if you know what I mean.
