Nothing big, what we see in the market with bitcoin and altcoins is the regular market moves. We don't have anything to describe in particular, as there is no big news associated with cryptocurrencies. Like the ICO and IEO that made a market rise, now the DEFI tokens were playing its role. As a part more such projects have gained good marketcap, this will last until something new enters the market.
I do not think that what we have saw during the last months can be attributed to their regular market moves that we see all the time, it is clear that the market is once again forming a bubble but instead of being a bubble born out of icos or ieos as it was in the past what we are seeing is a huge interest in DeFi projects, and while there are some that are without a doubt interesting there are many that are being released just because they want to take advantage of the fact that people seem to throw money at those projects without taking the time to research them.
