now only the price is little high , i think the value of the coin in future days may reach so high so that it would become so expensive to buy it
because now the people in the world started learning about bitcoin may it become popular
If the trend is going to be like 2017 then yes, there is going to be situations like only whales can offord buying huge bitcoins. I believe all who are earning bitcoin now, will have enough amount to buy and sell bitcoins. The circulation should be high when the price are so high and obviously the trade volume would be high as well. Hope to see such situation. If this situation happens then, other altcoins value would certainly increase as well.
