Looking at the tips you listed i will like you to add the one ultimate tip which never invest what you cannot afford to lose even if the assets is having a good history like bitcoin, investing in what you can afford to lose doesn’t necessarily even safe you from losing but actually keeps you calm even when the price dips and allows you to make better decisions.
For shitcoins, this statement is completely true but it may not be completely true for bitcoin investment if you invest rightly which is long term investment. Unless you are saying that bitcoin will seize to exist someday or turn to zero like most shitcoins do when held for a long time, this way I will say it will be difficult for that to happen. Bitcoin have come to stay and will not die anytime soon so we are not investing what we would lose but what we can set aside in an asset for a long period of time to reach our target in terms of wealth accumulation. I understand one could be expecting the investor to remove his mind from the investment for several reasons such to prevent him from selling it in the event of seeing so much profits or when there is sudden drop in price. This is why other control measures are actively being added into the bitcoin buying process as a protection of the investment. But my point is that investment in bitcoin have risk just like every other investment but holding bitcoin much longer reduces the risk.
