that's what beginners do without knowledge and find trading easy to do. indeed not all beginners traders are stupid in starting trading, but more of them rashly start trading and end up losing.
Rashly if they buy at the low price then they are going in the right direction, except if they sell early too not waiting for the price to pump upwards.
investing in Bitcoin like your advice is one of the best alternatives for beginners. though that doesn't mean it's easy to do. but at least investing in Bitcoin will make it easier for beginners to understand how the market and also the actual trading is done better. everything still requires a process that takes time and also capital.
It requires patience and newbies can build up their stash gradually depending on how they are earning a salary or collecting bitcoin from campaigns and all. Its a slow and steady race unlike some altcoins which imply a false get-rich-quick scheme and the eventual loss of newbie investment money.
We all have been newbie traders at one time or another. The important thing is the learning curve and the patience that made us separate from others.
