I am a full supporter of Oyster Pearl PRL so I could say, investing PRL this time still worth it because soon they will launch their main net to store files online through IOTA Tangle so therefore, PRL is one of the most underrated and most undervalued altcoin company today but in behalf of the team and the supporters, it will rise soon and surge the price to the moon in the next few weeks or months.
Oyster Pearl PRL and Shell SHL are both worth to invest this time while the price were cheap and affordable.
