I am familiar with people who also participate in generosity companies. Some of them do not rush to sell received Tokines, others on the contrary, immediately after the issue of tokens the exchange is sold. My friend advised me to send them to EtherDelta. When receiving tokens, place orders for the sale of x2 - x10 (depending on the project) and just wait until they are purchased.
What do you do with the received tokens?
In my experience, if an ICO succeeds to the extent that it pays bounties to bounty participants, chances are, the coin price will eventually exceed the ICO price. Some sell half of the coins to buy btc with it. I prefer to hodl the coins for some time, especially if the roadmap is particularly promising.
