No need to regret if you did not join the bounty campaigns and feel that you are left out on the tokens accumuation. It is not very easy to join the campaigns for everyone. By the way, the prices of these coins are still very low and you can buy these coins and keep them for the future. I am sure you will still earn a lot of profit by just holding these coins until they are listed on Binance or any other major platforms.
No need to dwell with the past opportunities but instead moving forward and try to see if you can take advantage of the current market, the value of those assets are still cheap compared to their last time high, there's always a good chance that those assets can rise high once it was added to binance, you can buy and hold till the value reached your target peak.
Do your DYOR and the rest will be passive for your investment. Keep on track of all the progress and activities. It gives a lot of positive vibes while holding your assets.
