Your advice has proven to be quite sensible in light of the rise and fall of Dogecoin - however there was quite a lot of money to be made if you were not too greedy. Those who held on while expecting to breach the $1 mark were the fish swallowed up by the investment banker sharks. However in the long run it seems to me that Dogecoin actually has a rather bright future precisely because there is a lot more in circulation and it replicates Bitcoin without being subject to the same level of rich people hoarding limited supplies. It is much harder to corner the market if the market is a lot bigger basically, so we might start to see a resurgence of certain "Meme" coins in future.
