Altcoin are growing due to market rise and crypto has a good value in the market so people come for buying now i personally invested in altcoin because i believe that crypto will be more good in future and altcoins are good for those who have patience and hard work. Now a days altcoin growth is started and soon it will be listed on stock exchanges.
This point where they sell is where we usually call the price correction, the reason why we usually see suddenly sharp increase in rice after price correction is because those investors that sold, are not selling with the intention of converting their holding to fiat and transfer back to their local traditional bank, but they sold in other to be able to accumulate more coin.
Therefore majority of them end up putting all the capitals and profits back into the market after they see a price dump. I am really expecting the price correction we get recently to help us push further as they put back all their investment with other new investors that will take advantage of the dip.
