I would suggest to you the XMR( Monero) because it has a lot of potentials and after the correction, the price will for sure start to grow. Bitcoin and Ethereum will also follow that pattern but I don't believe that the price will rise fastly for them. Try to make your own research and try to compare it to curves in the charts of the last 2 years. You will see the intensity of the fluctuation that prevailed in the price pump for the specific altcoins.
