It will work till first failure. First coin that will not bounce will zero your porfolio after months of buying more.
Risk that you take in this strategy is similar to hodlers strategy (
https://bitcointalk.org/index.php?topic=4456137.msg39881422#msg39881422). 100% of your portfolio. And you have no quarantee that your coin is good even if you did best research because.
1- whitepaper is just a document with words. It can be copierd and change a little. Faked. I can create myown whitepaper in which ill write that tommorow ill be on mt everest.
2-team can be faked with fake twitter account with bought fallowers
3- code - who of us can check if code is ok? How many of currencies have working code now? Most of them are just concept without working product jet.
4- hype can be bought.
5- beeing uniqe dasnt give you certainty of beeing uniqe forever. 1 month after your investment there can be new ICO with better team, bought hype and with working product delivered faster.
6- you are newbie and you did fundamential analys wrong or didnt do at all just jump after hype or because someone said that its great investment
7- there are 1600 coins. More than 1400 wont survive next few years because they are not neseesary. Your decision must be precised and full of luck
