I had previously doubted that Bitcoin would be replaced by another currency. But my mind has changed. Because I see there are many other cryptocurrencies that the developers are trying hard to solve the problems in cryptocurrencies. What about bitcoin? We don't know who are the developers and no effort is being made to develop it.
If you don't try hard, your rivals will win. Bitcoin's rivals will win too.
Mention us some details why will other cryptocurrencies replace bitcoin without any doubt, what has changed your mind so far?
Bitcoin maybe is not being used like before so often as the focus has been turned on to other altcoins which are taking all our attention with their ICOs, with their products linked to their tokens and so on, the ethereum network is really too much used and their are reaching their goal being the first one.
