I have made some good profits with the coins I truly believe in, still owning a good amount of that for HODL. I took a small percentage of my profits and been placing that 'play money' into some alts I think have potential.
I think were still at the beginning of something big here, there are still alts that will be really big in the future.
i did read your article and I think it is well thought. Upvote and follow for you!
