I heard about Shrimpy in this forum before but never really tried it.
Etoro is one of the known regarding investing and trading services so there are no questions about that.

Your effort is still needed to make the risk lower until almost zero.
Might as well do everything on your own instead of doubting one's work and doing it over again.
