Hello again....since i want to know what is bitcoin for you...and what you think about anothers cryptocurrencies like ethereum,litecoin,dogecoin,eth classic,zcash,dashcoin,monero,golem and others...
Those other cryptocurrencies are also good. They have the potential to develop and may surpass bitcoin. The only problem is that, of all the cryptocurrencies, bitcoin is the most famous thats why some other cryptocurrencies are not recognized and left behind. If we learn and study more about cryptocurrencies, we can realize that there are better cryptocurrencies that we can earn and use rather than bitcoin.
Yes .the cryptocurrencies other than bitcoins are also useful but the thing is that Btcs have the highest price in the market and therefore the whole of investment market shows some type of inclination towards this currency. But, if other currencies would get started to be used in the payment methods on a large scale then obviously their value could also increase in terms of dollars and must become competitive for bitcoins.
