If you want coins which have 100X or higher potential then I would suggest the following ones:
Oyster Pearl (PRL)
Blockport (BPT)
Matrix AI Network (MAN)
All of those 3 projects are massivly undervalued. Especially MAN has massive potential to even become a top 5 coin.
But as some others suggested, make sure you mix things up. Going all in on one coin for 1 year is a massive risk no matter which coin you pick. Split your money across at least 3 coins.
