I have to admit I've started buying untamed booster packs using paypal.
Why?
A. Because I haven't found a more convenient way to enter the crypto space using PayPal.
B. I know the value of the booster packs will eventually go up (unless splinterlands falls apart for some reason) and I can sell it for some nice Steem with very little upcharge (I think 1% to remove from Steem-Engine).
I think the largest part of starting a successful SMT is figuring out what will give it value.
value seems to be the hidden key
