Do I understand it correct that in the ICO we can buy only LVL tokens, and if we would like to have profit sharing, we have to transform them (or exchange them) to the LVLS tokens?
Which is the best token to buy/hold?
Yes, you are right. During Presale/ICO you can buy only Utility token LVL - this is basical token.
It gives you an opportunity to use all LevelNet platform services, such as LevelNet application, access to the Buyback and Money Back Guarantee funds.
And only being the LVL holder you'll possible to exchange it for Equity LVLS tokens.
Owners of LVLS will have ownership and profit sharing rights, owners will have rights to be chosen in supervisory committee, to nominate the members of the Director Board, to choose the Funds main investment and expenses directions.
!!! There are no way to buy LVLS token bypass buying LVL !!!
So, the only one correct answer for your question "Which token better to buy" is: first of all you need to buy LVL tokens
