Probably you wonder what are the ACE tiers, I do to few days ago so I go to investigate it. In a few words, ACE tiers are an incentive to buy the tokens earlier in the presale and hold them. That is it, I promise you that is the core, so you can now go to do another thing. But, if you are a curious person or you want know the specifics keep reeding this post.
First at all, ACE have six pre-sale tiers. Each one with a limited number of open member position to ensure scarcity and urgency. Also each tier have specifics benefits, while higher the tier more benefits you enjoy. Of course yuo only can reach a tier during the pre-sale. Let´s breaking tiers down.
- No tier: Small holders with less than 100 ACE, being here don´t give any extra benefit. Just the general pre-sale ones (10% APR for single side staking and up to 20% APR for put liquidity on LPs).
- Ant: Holders that have between 100 and 499 ACE tokens. They will have $2K lending access, a 8% borrow rate. The member slots for this tier are 5000 (limit only for the total amount of the pre-sale).
- Raise: This is the holder range from 500 to 2499 ACE. You get $8k lending cap and a 7% borrow interest rate. Also when you buy in the presale 1K or more you can get a 3% bonus of all your buys. This only have 150 tiers slot open and already 10 are occupy.
- Shark: hold +2500 ACE give you $16k lending access with 6% interest rate. You can get between a 5 and a 7% bonus of all your buys. It have 50 slots and 1 is currently occupied.
- VIP: 9000 ACE or more to join. Have 10 open slots that give you $30K lending limit with a 5% interest fee. Beyond 10k you can get a 10% bonus for your buys.
- High Roller: 45K of ACE buys during the pre-sale to join with only two open slots. This gives you a 60K lending access with just a 4% APR borrow rate.
The tier status that you get it´s a lifetime one. Currently I see difficult that somebody reach the VIP or High Roller tier inside Hive, that tiers demand an amount that it´s to big inside this niche.
As I first say ACE tiers are an incentive to buy the tokens earlier in the presale and hold them. Accordig to your liquidity and long term objectives you can choose to which tier belong. You can also start to buy cheap LEO right now, because that will be the collateral to the 
I hope that you understand now better the tiers and what they are. Your comments will always be welcome.
