Not all crypto coin will survive. Most of them lacks of real live application which  leads to the death of the coin. This usually happens when the promotion is not that good to produce poor amount of supporters/ community

It can't be. Since the price of bitcoins constantly change that follows the transaction fee.

Since the common currency that an average person used is the money in paper (depending on the country). Some people may hard to comprehend the currency that don't have physical form, in addition you have to be familiar on computer or any gadget to use bitcoin. For some people this will be a pain on the ass that will result them to give up

This is good for a beginner like me. Thanks
