This possible situation can happen but I hardly doubt it that any coin will surpass the Bitcoin and take it off the market charts throne. Although the Bitcoin has some big problems right now that are including the high fees within the transactions developers are hardly working on the improvement of this issue. The lightning network will be issued soon and that will for sure change the standards on the market.

I predict that the Bitcoin will surpass its limits and that it won't be achievable for any coin to match the Bitcoin in the value.

I think the transfer fees will decrease and the number of transactions will increase if the BTC price stabilizes. For this reason, I do not believe that BTC will be a more valuable coin. BTC can be more successful coins but BTC is always king.

Yes bitcoin is the king of all crypto currencies, but think of if, if someone invented an cryto currencies that has all the advantages and resolved all the disadvantages of bitcoin, I think that is the time bitcoin will be dethrone.

I don't know, I just thinking the investors who come to invest in the world of cryptocurrency they just know bitcoin, they never know about altcoin that outperforms the bitcoin especially in transaction process problem. Or because bitcoin price have a high value so makes investors more inclined to think that bitcoin investment is very profitable compared to the price of altcoin which is still below $3000. But I know in this world of cryptocurrency bitcoin has a big influence on the price of altcoin, exactly if bitcoin prices go down automatically also altcoin prices decreased. So, the deficiency of bitcoin is just in the transaction procces compared with some altcoin, and this can be overcome if the successful lighting network is launched.
