Don't do that dude. Don't go "all in". I have done it before. I have invested my 20k to titanium (BAR) which was very very promising token 1.5 months ago. And then it was hacked. Now I even cant sell them 4k.
By bad chance.
Have to agree
Why not buy 1 BTC 1 ETH and then spread the risk/reward. 90% spread evenly across the top 10, and then 10% across under 50 cent projects you can be passionate about who have something to show they have built. (I personally did this with Singularity NET)
