Finally, should I do it now that the price is not stable or I should wait a little in case it goes down again? We are all here to learn.
Since others suggested the best wallet already. Now I think tou shouldnt wait or assume its already high or low. No one can accurately predict that but I suggest that if you have fund on a regular basis do a timely buying of bitcoin like averaging so that you could buy at cheaper or if does goes down youll get cheaper. But for now bitcoin is totall fine and still far from ATH.
My advice to accumulate bitcoin as a newbie would be to spend time researching and participating in forums etc and you will accumulate satoshis at the same time that you accumulate experience and knowledge. If you spend time learning you'll earn bitcoin one way or the other.
But if you are looking for simply investing your hard earned money then yes, go for a hardware wallet and try to predict the market, although it will be a bit like a lottery. Another option is to buy little bitcoin and reserve some cash in the event the price goes down and this way you'll be averaging down the purchase price.
Correct. I agree too. additional advice from me to OP is to always prepare fresh funds in case of a decline at any time. yes. it's better not to rush in and apply directly to the application of the price set pattern below, slightly lower than your trading APP screen display (if using an Android phone). once touched set sell back at the highest price on your APP Trading screen display. That's how to accumulate the value of your assets to increase. for now it is worth a try.
