Op when you was asking for accumulation, that time was perfect for investment. Cause that time price was low. And then price gradually started pumping. now altcoins are very high of their price if compare now vs the time you posted. But don't lose hope. You can also buy if you didn't get anything yet. Top coins like ether, bnb, ada, matic should get more priority than others altcoins cause they are more safer then others altcoins. Besides buy some potential altcoins if you already aim to buy after your analysis
The expensiveness of the other major altcoins means that they're good if they have started from a very cheap price.
ETH for example has been there like became $10 on 2016 to early 2017 and then look how much it's priced in now.
The same goes for the other altcoins but not all of them are worth it, the liquidity is there and all you have to do is to decide what you'll buying with how much you've got.
