Hey mate,  don't slap yourself so much because you were on able to choose RLB against the other tokens you chose,  it is what it is regardless and since the market is unpredictable just like gambling results,  you have to always forgive yourself whenever you failed to make the right selection regardless of what the result may be at that point,  and also sometimes utility is not the only feature to look out for when selecting a token to hold,  although the utility is also important you have to check how the token road map fits into your bearable waiting time and how much time you are willing to spend in waiting for the price to reach your speculations.

Secondly, it is not too late to buy any token unless you are sure that the current price is already at a pumped price that will make it impossible to achieve another lent of such a pumped price,  but if it is still at its basic price pick up level,  then you may still be at a gain position regardless what the current market cap is.
