Being top 50 are not is not a big concern as far as I have seen how few tokens are showing good growth in short period of time itself. But, you must take time to research and analysis how effectively their team is working and what are their future plans mentioned in their roadmap and how actively they are providing updated about their progress and many more things that we need to follow before deciding to invest with a token.
Do you have any reference for the tokens you are mentioning for fulfilling the points that I have referred to. Without doing any proper research and analysis, investing with them will lead to big losses because you are risking with almost non-familiar tokens.
Definitely I will not invest with non-familiar tokens. Moreover I do not have any plan to invest into any new altcoins nor tokens. Because as per the lessons I have learned in recent past , I must avoid all the altcoins and tokens which includes all the POS coins and masternode coins too.
I just suspect that OP is here to promote some of his tokens or where he already invested. This is not a new item because I do seen lots of people are doing the same. You just need this community's support to back them up. It means they indirectly convince us to invest where they have already invested so that they will reach their selling price levels.
