In the future，BITCCOIN Will also continue in the position of the virtual currency system Ranked first?
bitcoin is not a "virtual" currency it is a real currency. it doesn't get any more real than that.and so far bitcoin has been and still is the onlycryptocurrency that exists. all the rest are trading toys called altcoin which are falsely using the word coin or currency in their description.
Although most of the virtual currency acquired from BTC the original design, but the virtual currency would significantly more than BTC development.
i don't understand this sentence 
The intelligence of the ETH contract, for example, the DASH of pos node development are far more than BTC
if you really think that, and if you are really ok with a centralized coin and a coin with a significant amount of premine, and a coin that has whales controlling the price and pump and dump it 50%-200% then go ahead and use them nobody is preventing you 
And BTC is now facing a simple Blockchain congestion problem
the only problem that bitcoin is facing is the spam attack and nothing else.In the future, all kinds of virtual currencies rise, BTC will in no. 1?
duplicate of your first question!Yes, BTC is indeed a pioneer, but 1 MB Blockchain, bring me a lot of trouble, but also accelerate the confirmation fee is higher and higher
it is not the 1MB block size that "brings you a lot of trouble" it is the spam attack and there is a big difference.makes me have to choose other virtual currency for transfer of property 
what other altcoin did you use to transfer! and who even accepts them in the world! nobody that's who
