Greetings friend @xpilar.

Excellent your participation, your comment could be considered as advantages and disadvantages of each of these support strategies.

The trail is usually more efficient the higher the SP of the users and the percentage of vote assigned to it. The best thing about the trail is that it promotes the support of all for all, where everyone wins equally and where the main account is only a guide and not a reward center.

On the other hand, the Delegation obtained as a form of rent seems to be not very profitable for those who receive the delegation SPs, it is very important to know these percentages handled to obtain delegations.

We appreciate the contribution of your good participation amigo @xpilar.
