The best advice to follow is to see bitcoin as a long term investment vehicle. Ignore all outside noise, FUD & short term price movements. You will not lose money if you buy bitcoin & hold it long term. For any noob, just starting to buy now, it might be hard for you to become rich by buying only bitcoin in the short term but if you buy bitcoin regularly over many years you will be in a good position.
Save bitcoin alongside regular monthly fiat or pension contributions. 20 years of DCA (dollar-cost-averaging) monthly into bitcoin will put you in a nice position to enjoy a comfortable retirement.
Bitcoin has prospects for the long term and we must have a goal of at least 5-10 years to invest in bitcoin and this will mean much more than the short term, about noise outside or even negative news that makes them panic we must be able to refrain from that situation The most important thing is never to store assets on an exchange, so we will not lose them or their value because bitcoins are still bitcoins if they are not sold.
True, if I buy the average bitcoin (DCA) from now to decades to do this it is the same as saving money for our retirement later, in fact it will be worth more than saving fiat which will become inflation.
Well, the best way is DCA (dollar-cost-averaging) or weekly or monthly if it becomes a routine, our bitcoins will accumulate in old age.
