Hive account@nixeus , Hive account@feelsomon Antshares can be bought in any size but be careful when you withdraw from bitrex to your antshares wallet because only whole shares will be transferred and the rest will be lost.

For example if you have 10.80 ANS in bittrex and you want to withdraw, if you fill 10.80 in the amount field, they will take 0.35 ANS as a fee and you will get only 10 ANS, the rest 0.55 ANS will simply be lost.

So, in conclusion, you should fill the amount with X.35 ANS and whatever is left just keep it in bittrex or convert it to another coin and withdraw after.
