Buying 150,000 #ALIVE is a tall order.

Hive Engine says that the supply of ALIVE is 1,745,623. 150,000 ALIVE is 8.5% of the supply.

The ALIVE richlist is a good resource.

The @null account has 54K ALIVE. That guy is really stingy and doesn't ever sell his coins.

I sorted the richlist by balance. I am not sure if there is a total of 150,000 ALIVE for sale.

I then sorted by stake.

I see that you are in position 8. The largest stake is 115K.

So, I would say your goal of buying 150K ALIVE at this point is unfeasible ... unless, of course, you are able to talk the owner of the account into minting 150K ALIVE.

My guess is that you already knew this.
