In trying to put more pressure on the market by constantly monitoring a supposedly long term bitcoin or cryptocurrency investment, one ends up putting pressure on themselves as, the market is and will always remain a collective effort from the whales to make any huge difference.
The market is a highly volatile environment and most times more than anticipated, it always looks as though your loosing, as though it was set against you and that builds pressure on you as an investor. Pushes you not to invest or sell your crypto portfolio due to phobia of further falls.
Staying away the charts becomes a reliable strategy to be in the market not minding the market condition.
I agree, if we're not daily traders and prefer long-term then it's better just to buy now and come back after a few years when we hear another bull run. There's a lot of FUD out there that makes new investors afraid to wait for long term since they're new to this high volatility. If we don't have enough experience that builds our mentality it's better to invest for the long term and pick the best altcoin according to coinmarketcap.
