Absolutely. Very sound advice....sadly, most will not take it. We will continue to read about the horror stories of people getting bilked for millions of dollars.
Personally, I do not touch ICOs since I have no where near the ability to judge a good one from a bad one. There are a lot of projects that sound good which will fail miserably. Some due to the fact they were scams from the beginning. Others, and most likely more common, because even though there are the best of intentions, there simply isnt the expertise to deal with the challenges a new blockchain has.
People need to stop getting caught up in the euphoria. In the last couple months, the only thing I bought was STEEM and BTS, two tokens I believe in. Over the past month, with the major run, I put no fiat in. I am at a point where I have some cash to buy in again, but I am taking it slow before I jump. A big pullback in one of my core holdings might cause me to add or I might do another token...but it wont be blindly.
I´m as well not investing in any ICO´s anymore at all as like you say it´s really hard to judge them and even in case they sound promising it could still be a scam or the project doesn´t get far as the founders don´t really push it after making a bunch of money...
Steem and BTS are as well my two biggest holdings and just like you I strongly believe in their major success within 2018 and beyond. We´ll see prices in future that are far away from the ones today. I think your estimation is about 100$ for the near future, which would make everyone who owns 1.000 Steem a wealthy individual :)
BTS has definitely been more frustrating lately, I actually really love the exchange and am surprised there aren't more people on board. Seems like people just go with the FOTM or whatever is being hyped instead of looking at the actual products. I'm waiting BTS out though, @dan and co seem to always create great products, I'm most hyped for EOS even though it's a ways off
Most of the good looking ICO's you can't even invest in (well there are work arounds). I already made my picks, now my main focus will be on watching those coins and steeming to generate steem. I want Steem to be my largest % of my portfolio.
