Bitcoin will remain the only solid coin. The only coin that survived for the longest time (other coins can't claim this unless they invent a time machine).
There will be alts that pump really hard and make people millionaires, but no alt is going to surpass Bitcoin's strength and solidity. No coin will get a bigger marketcap. In the long term people holding 21+ BTC will be rewarded by history with rich-tier status for seeing the value in it before most people did. Do not let the FUDsters trick your mind or the trolls try to derrail the excellent job being done by Core devs.
Let's continue then our path towards inevitable triumph.
Maybe you have a point in all of this your statement that as of now no one could not surpass the price value of bitcoin,but we always remember that theres a big competition in block chain market of all crypto coins and we could not guaranty that all the times bitcoins is still leads in coin market caps,because maybe someday when we woke up,theres a new altcoins would replace bitcoins in its postion as a number one crypto coins in the market,maybe not now but maybe soon and we could not guess the exact moment when should it happen.
