TomoChain showed amazing performance recently it is happening because of some upcoming events and their solid direction to make this blockchain more secure and useful. It seems it still has big scope to achieve more value from my point of view this is hidden gem with huge potential to explode so huge.
In fact Tomochain has and will has more usefull things that most of the top 20 coins. So it will be in top 20 soon. Its just matter of time I guess
