If it is a question of altcoins and especially the LTC it will be very possible increase 2x not 7x, something I observed in the world of altcoins: " any good news can cause the price to increase more than 2x if the altcoin has a big community and a great team " so I believe it to be possible.When I invested in Verge I had a profit of 3x in a few weeks and I made a lot of profit in another currency that I invested so I realized that the crypto world is only dominated by the news to cause the price increases or decreases
