Purchase a tiny amount to get you started and lay the groundwork. It is preferable to invest now and hold for the long term if you have chosen a decent currency. If you try to timing the market, you risk losing out on the opportunity to acquire the coin at a better price in the future. Ideally, you should buy a cryptocurrency while it is cheap and then sell it after the price has grown significantly.
Profits may be taken in Bitcoin, which can then be used to invest in new cryptos or expand your present altcoin holdings. If your investment has grown significantly (10x-100x), you may cash out your earnings in Bitcoin or Fiat and reinvest in the same currency when the price falls.
