In fact, in terms of pricing, bitcoin prices tend to increase significantly compared to altcoins. however, I have the same perception as the OP. currently I can't get bitcoin because of its high price. we may have it in a small amount, but we are looking for a large profit, with minimum funds. however, I still choose altcoins now because the potential for altcoins is quite large, and the price is still quite affordable.
Exactly, people who have an idea about what was happening in the year 2017, it is not a good idea to invest in Bitcoin when it is at a high price. Better focus on other potential altcoins which has a higher probability of chances to increase their prices, still those coin prices are cheaper in the exchanges which we can afford them.
